My problem is:  
When connecting to Mautic, I get a ERR\_CONNECTION\_TIMED\_OUT on login page and wont appears anything.

Tried to update using command , but got error

These errors are showing in the log:  
No error on /var/logs/

Steps I have tried to fix the problem:  
Removed from Cloudflare (direct to server now)  
Fixed permissions, and tried to update

Anyone can help me with these errors? Thanks!
