Zoho Mail Android app: SSL Handshake error

Yesterday the app stopped working. Refreshing didn't work. After I signed out and tried to sign in there was an error: SSL handshake error. I couldn't sign in.

The app seems to be working on ipad and on android 9. On my android 5 the app is not working anymore. I have also uninstalled the app and installed it again. The same error after I've tried to sign in.

Please advise me how to solve the problem. Thanks.
