PC client update auto and users can not login in with the new version client

Nextcloud version (eg, 12.0.3): 12.0.3
Operating system and version (eg, Ubuntu 20.04):linux
Apache or nginx version (eg, Apache 2.4.25): apache 2
PHP version (eg, 7.1): 5.6.31

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N):Y

Steps to replicate it:

  1. we use the client version before and it works well,and yesterday the client update to version 3.0.2. We can’t prohibit updates.
  2. with the new version client, I put the server host :http://IP:port,and next put the username and password,click login,and the client always show ‘jumping’ and can not login

The problem has been resolved, I use nginx, and use https.so the new version must use https
