Upgrade to 15.02 cant access web front end (HTTP ERROR 500)

Nextcloud version (eg, 12.0.2): 15.0.2
Operating system and version (eg, Ubuntu 17.04): ubuntu 18.10
Apache or nginx version (eg, Apache 2.4.25): Apache2 2.4.34
PHP version (eg, 7.1): 7.2.10-0

The issue you are facing:
I updated the Ubuntu server and after the update everything was working ok. When I installed nextcloud client for mac I immediately received the “HTTP Transmission error happened. The server file discovery reply is missing data” this appears on the client application only. I searched through forums, etc and found that its possible that the server needs to be upgraded (I was on 15.0.1). nextcloud showed that the update to 15.0.2 was available and I performed the update. the update said it complete successfully. A reboot was required. After the server came back up I can no longer access the webpage (HTTP ERROR 500) and I I still have the “reply is missing data” error on all mac computers. I see that this error might be caused by the google drive app, which is installed on my system but not in use. I don’t know how to remove it if I can’t get into the GUI. any help would be appreciated. Thanks in advance.

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