Hello @aigyr

You seem to be using Document Server, is that correct?
Please specify the version of it and also type of installation (Docker, DEB/RPM, exe). If possible, please share the link to the guide that you’ve followed to install Document Server.

I am using version 7.4 running on Docker

Please try accessing Document Server via IP address/domain name of the machine instead of localhost.
