Can you please add PGADMIN_CONFIG_CONSOLE_LOG_LEVEL = 10 in the environment variables and restart the container? 503 errors because server is not connecting.
Above settings print logs in more detail?
Can you please share docker command or docker compose file used for starting the container.
I've been using pgadmin for a while to connect to my PGS server (both in docker containers) including very recently; today however, randomly, all I get is a rapidly spinning "wait" icon over the server when trying to connect: (see attached screencap)
It goes on perpetually. I have made no changes in settings, and the logs for both PGS and PGAdmin show nothing in terms of errors or issues.
I'm updated to the latest versions of both software.
