503 Service Unavailable for Web Admin

[arithmatics]

After migrating wordpress to a new server created via the openlitespeed wordpress deployment on GCP, I cant access my web admin.

After checking /usr/local/lsws/logs/error.log this is the output:

Is there anything i am missing or can try and troubleshoot?

Default wordpress image on GCP has port 7080 disabled, so, do you have port 7080 enabled on the system? See https://docs.litespeedtech.com/cloud/images/wordpress/#web-server-control-panel-access

Yes I have it enabled.

It's wierd because this was a wordpress installation migrated from an older server. I moved the databases and all that was required.

when i run

sudo tail -n 20 /usr/local/lsws/admin/logs/error.log

this is the output after opening http://<IP>:7080

2025-08-06 10:47:48.601383 [NOTICE] [206161] [101.53.219.160:17830:HTTP2-1#_AdminVHost] oops! 503 Service Unavailable

I have checked the status too by running:

sudo /usr/local/lsws/bin/lswsctrl status

return:

litespeed is running with PID 206159.

I've tried restarting, rebooting the server, and each time it still returns the 503 error.

I'm going to try and migrate again but to another new server to see if the issue persists. Perhaps my backup is faulty.

It looks like a php related issue. But a site migration should not cause such an issue.
On the new server, please make sure the web admin is working properly before doing the migration.
If the webadmin is not working, let me know.

Okay I've just migrated to a new server from a backup which was a machine image. everything seems to be working fine.

I remember too that during the migration I moved it into a server with a lower number of vCPUs and RAM. My OLS server configuration were all still the same on the higher end server.

This new one I have kept all the instance settings the same. I'll test to see if I really needed to change some of the webserver settings opcache, php connection limits, etc. before moving into a smaller server.
