Hello

I am getting

Server Error

502 Bad Gateway​

Web server received an invalid response while acting as a gateway or proxy server.

https://15.235.83.79:8443

I cant run repair kit as it says its missingi have tried in ssh

I noticed a file was renamed to ervice sw-engine start I dontknow if the file name is meantto have an s at the start

my websites are running is this because im lacking storage space? im deleting files from the server but i cant log on to my CP

 

[Peter Debik]

Could you please rephrase your question? Are you asking why there is no storage space left or how to free space?

 

[mmandmppro]

im asking how to fix the error which i said at the start of the message

If I'm reading correctly, plesk panel is giving him an HTTP error 502.

If you're able to connect via ssh I'd recommend trying to run: plesk repair installation

Running
# plesk repair
is "missing"? What is the exact output when you run it?

Have you already freed space on disk, e.g. by removing no longer needed log files from /var/log?

I have deleted no log files as i donot know what log files i would need to delete, the error started after i tried to download a 1.2 tb backup and got a time out

Cause: /usr/lib64/libaps.so.1 is a symlink to /usr/lib64/libaps.so.1.0, which does not exist.

Your installation seems badly damaged, because if PSA database is missing AND files are missing, probably more than just the above mentioned file is missing or corrupt. You can try to fix that one file as follows:

# ls -l /usr/lib64/libaps.so.1.0
ls: cannot access /usr/lib64/libaps.so.1.0: No such file or directory

Resolution:
Connect to the server via SSH
Create a temporary directory and navigate to it;
# mkdir plesktmp ; cd plesktmp

Download the libaps from http://autoinstall.plesk.com/PSA_[PLESK VERSION]/dist-deb-Debian-10.0-x86_64/engine/libaps*, for example, for Plesk 18.0.52 and Debian 10:
# wget http://autoinstall.plesk.com/PSA_18...libaps_1.0.12-debian.10.230222.0826_amd64.deb

Copy the new file to the live directory:
# cp -a usr/lib64/libaps.so.1.0 /usr/lib64/

Restart the psa service:
# systemctl restart psa

Important: You named "Plesk 20" as your Plesk version, but there is no Plesk 20. The latest version is 18.0.52. You must know the Plesk version to apply the above commands. In the above commands I assume that you have Plesk 18.0.52. If not, please replace the PSA_18.0.52 with your correct version.

If further errors exist I strongly recommend creating a ticket with Plesk support.

i do not know the plesk version because i cant log on to plesk to see the version

 

[Peter Debik]

Please run
# plesk -v

 

[mmandmppro]

Product version: Plesk Obsidian 18.0.49.2
OS version: Debian 10.13 x86_64
Build date: 2023/04/04 10:00
Revision: 5f28ac65ab7698d3411bcb7b25e11dabc0d59dd9

 

[Peter Debik]

Well, then it is Plesk 18.0.49

 

[mmandmppro]

i deleted a load of files from psa thinking they were just dump files from my back ups i do not know if i have a copy of them

 

[mmandmppro]

root@ns5016732:~# mkdir plesktmp ; cd plesktmp
root@ns5016732:~/plesktmp# http://autoinstall.plesk.com/PSA_18.0.49.2
-bash: http://autoinstall.plesk.com/PSA_18.0.49.2: No such file or directory
root@ns5016732:~/plesktmp# autoinstall.plesk.com/PSA_18.0.49.2/dist-deb-Debian-10.0-x86_64
-bash: autoinstall.plesk.com/PSA_18.0.49.2/dist-deb-Debian-10.0-x86_64: No such file or directory
root@ns5016732:~/plesktmp#

 

[Peter Debik]

i deleted a load of files from psa

In that case you need to reinstall your server and restore contents from a backup.

root@ns5016732:~# mkdir plesktmp ; cd plesktmp
root@ns5016732:~/plesktmp# http://autoinstall.plesk.com/PSA_18.0.49.2
-bash: http://autoinstall.plesk.com/PSA_18.0.49.2: No such file or directory

You're missing the "wget".

But again: If you have removed not only that one file, you will very likely need to reinstall the server, install a fresh Plesk on it and then restore your content from a backup.

 

[mmandmppro]

I only removed files from the psa directory no where else as i was deleting dump files
