While having proper access through the browser on both the PC and the android phone, connection using the android app fails claiming “error when verifying server version”.

My android app is version 3.5.1 and was downloaded from F-DROID. Is the difference between app version and server version (3.5.3) causing the problem? Should I somehow downgrade my server version to cater to the app version? Please help.
