502 bad gateway problem

debian 10

PROBLEM DESCRIPTION

Hi,
It looks like I'm stuck with a 502 admin login page only giving me option to log in to the repair kit, and I cannot log in to that either.

via ssh it's not possible to restart sw-cp-server

the journalctl mentions license problem, but I do have a valid license.

Is there something obvious I'm missing?

STEPS TO REPRODUCE

when I run journalctl -xe

ACTUAL RESULT

~$ journalctl -xe

Help with sorting out

 

[Bitpalast]

A reboot of that instance might solve it.

 

[Tempest]

unfortunately it hasn't.
It actually was triggered by a reboot. But I tried again, also using a snapshot from before it happened. none worked. Another thing is Plesk couldn't update since August.

Hi, @Tempest . The errors you get:

Nov 28 03:29:19 vps-17cc9899.vps.ovh.net sw-engine-pleskrun[27588]: /usr/bin/sw-engine: /usr/lib/x86_64-linux-gnu/c++-plesk-13.3.0/lib64/libstdc++.so.6: version `CXXABI_1.3.15' not found (required by /usr

could be due to package corruptions, duplicate packages, repository misconfiguration, etc. I can't easily identify the exact cause for the issue. If you have the option, I would suggest opening a ticket with Plesk support for further investigation with server access.

What you can try removing sw-engine and re-installing it according to:

Hi @Sebahat.hadzhi, thanks that was helpful. Not out of the woods yet.

It looks like the Plesk version installed is 18.0.72:
cat /usr/local/psa/version
18.0.72 Debian 10.0 1800250915.05

but the sw-engine version installed is from 18.0.71:
dpkg -l | grep sw-engine
ii sw-engine 7.71.1-debian.10.250709.0854 amd64 Plesk panel interpreter

so, I tried to remove that and install the one from 18.0.72 as per the article link you posted.
But during installation 5 libraries dependancies mismatched as being from the previous version:
sudo dpkg -i sw-engine_7.72.1-debian.10.250807.1639_amd64.deb
Selecting previously unselected package sw-engine.

dpkg: error processing package sw-engine (--install):

Would you have advice on the best way to mix the mismatch?
