Error after updating to v3.2

My suggestion is to delete the .lic files, under /home/ubuntu/.local/share/WebGrab+Plus/License or the root/user you use to grab. Then run a force license update.

Are you sure that when you updated, you copied also the dll files (all the files) into .wg++/bin ?

I think you using docker or you reformatted your pc....license had similar ID and got blocked, run a force update license and should be ok

I got this error after updating.

did you update all files ? what is your system ? can you post WebGrab++.log.txt ?

Yes, I replaced the /bin contents with everything from "WebGrabPlus_V3.2.1_beta_install.tar.gz"

I am running it on Linux / Synology

this could be also an issue with connection. Can you try to ping google.com from /volume1/tv/wg ?

i don't think so. connection works well. ping is not permitted but wget works

ok..what site are you trying to grab? can you try with sample config https://github.com/SilentButeo2/webgrabplus-siteinipack/tree/master/site...
Although i think is a connection problem (i had this sometimes in windows using vpn), so would be good if you can try on your pc first just to make sure it all works.Make sure your dns is set to 8.8.8.8 and 208.67.222.222.
Last also have a look in forum for synology posts.
ps
welcome to the club

thanks for the welcome.

it fails with any site i try to grab. but here are some examples:
<channel update="i" site="srf.ch" site_id="eurosport" xmltv_id="Eurosport">Eurosport</channel>
<channel update="i" site="uk-sky.com" site_id="2076" xmltv_id="BBC 1">BBC 1</channel>

it doesn't even grab the license, as the license log looks like this

[ ] WebGrab++ license request and update log
[ ] 2021/08/04 12:10

so i think it fails before getting to siteini, maybe fails during license check or even before, very early on.

i suspect this might have to do with mono 5.20 for synology, as same 3.2.1 version works on my mac with mono 6.x. unfortunately, there is no newer mono than 5.20 on synology...

could you test your 3.2.1 quick fix with mono 5.20?

thanks!

i don't think is mono related, rather i would make sure your synology dns is set to 8.8.8.8 and 208.67.222.222
Talking with Jan (he had a synology) he mentioned he had problems with wg crash due to DNS.

Set the synology DNS to 8.8.8.8 and 208.67.222.222 as suggested.

nslookup wgpluspluslicense.file.core.windows.net
Server: 8.8.8.8
Address: 8.8.8.8#53

Non-authoritative answer:
wgpluspluslicense.file.core.windows.net canonical name = file.ams06prdstr12a.store.core.windows.net.
Name: file.ams06prdstr12a.store.core.windows.net
Address: 52.239.143.200

Unfortunately it still fails with the same error despite this DNS setting.

Also tried with the suggested "WebGrab++.config.example.xml". Same issue...

TheTinkerer wrote:

I’m now getting the same error greenmountain is getting unless I start the grab manually.
So whenever it starts through crontab I get that error.

Strange, how do you run it manually ? with "./run.sh" or with "mono WebGrab+Plus.exe" which user do you run it manually ? also is cron under root or user ?

crontab -l will list your crontab, you can check both when you run as root or user
chmod only set as executable does not change owner

Any more thoughts or updates on this? Is there any new patch prepared to deal with the issue? Thanks

this happens due to old .license files (you can delete them in /home/(user/root)/.local/share/WebGrab+Plus/License/) or due a missing contact with azure server for license, most probably a dns problem.
i have also seen it running wg on unix first as root and then as user (permission on files problem).
besides this 3 factors can't think of anything else, but it is strange as there are other users that have wg working on nas.

Windows antivirus stopped webgrab+plus.exe because

Trojan:Win32/Wacatac.B!ml

I deleted the /home/(user/root)/.local/share/WebGrab+Plus/License/ folder (it was empty). I gets created after each failed run, but empty. No .license files inside...

The DNS is set as per your earlier suggestion

Set the synology DNS to 8.8.8.8 and 208.67.222.222 as suggested.

nslookup wgpluspluslicense.file.core.windows.net
Server: 8.8.8.8
Address: 8.8.8.8#53

Non-authoritative answer:
wgpluspluslicense.file.core.windows.net canonical name = file.ams06prdstr12a.store.core.windows.net.
Name: file.ams06prdstr12a.store.core.windows.net
Address: 52.239.143.200

it's empty as it is unable to contact the server, it is strange because if you run siteinipack_update.sh you said it works.
Some user had to create symlinks and make storage mount with smb (http://webgrabplus.com/content/error-after-fresh-installation-synology-nas)
last you may want to contact the authors to see if anything wrong with your license

Thanks. There is nothing wrong with the license. As said earlier, it works on the Mac, in the same network, same 3.2.1 version, same config and with the license I have. I continue to suspect the Mono version, which differs between Synology and Mac, or some corner cases that 3.2.1 Beta doesn't resolve. I don't exclude some permissions issues but I checked everywhere in the /wg folder and the permissions seem ok for all files.

I have webgrabplusplus in the docker on Synology NAS, after the last UpDate, unfortunately the webgrab does not work. A similar problem to one of the people above.
I tried to delete WebGrab completely and installed a completely new copy. Unfortunately, nothing helped. Everything was working before the last update.

have you guys tried more then one time? I am with windows laptop connected with cell phone hotspot and i had this problem once...
ps
docker we know creates multiple id, therefore a quick solution is reset the hardware mismatch with license update h

just tried again, same error.

on my side, I use synology but no docker

If there is a way to enable more detailed debugging, I am happy to try it.

It is the same error on docker in ubuntu. I rolled back to container version to "ghcr.io/linuxserver/webgrabplus:version-V3.1.8" and it works normally again.

@wampas - Thanks a lot! That was a great tip. I also reverted to 3.1.8 and works like a charm! So to me, there must still be an issue introduced in 3.2 / 3.2.1

Same issue here running on Debian 10.10 with Mono 6.12.0.122 and coming from wg++ 3.18 heading for 3.2.1:

Previous installation with 3.18 works flawlessly, licensing is fine as well as internet access.

Any help would be greatly appreciated.

can you post full log? also do systemd-resolve --status | grep 'DNS Servers' -A2
to see if you have correct dns

Hello Guys,

first of all thanks for all the good and fast support you give.
Unfortunatly I am having the same problem as descirbed in the first port here. And I have already updated to 3.2.1
I am running the Grabber on a Windows 10 System.

Eventually it can help also as I am only seeing linus systems with the same problem.

The Update of the Siteini runs without problem, so a connection problem can be excluded.

Please help and tell me what you may need more to find the problem.

@mat8861 unfortunately there is no more info in the log:

systemd-resolve returns my local router for DNS, which is correct because all DNS is handled there.

Cheers,
Ole

dns should return
DNS Servers: 8.8.8.8
208.67.222.222
DNS Domain: ~.
root@ubuntu:~#

sorry i posted an old link, we are testing on linux several version....be patient.

Why should it do that? I'm not using Google DNS and external DNS services are not reachable on my internal network because of firewall restrictions.
My router is handling all DNS requests (internal domains and external services) so I don't have any need to even query
external DNS services on my client boxes.

BR,
Ole
