issues after migration to digitalocean

Hello, I'v been getting server errors 404, 500 and problems with google ads not showing up, the problem appeared after migration to digitalocean the same issues are in my apps IOS and Android as well, I want someone to fix all problems in the website and apps bot android and IOS, and there is also jquery and google maps issues/warnings, I included screenshot from error log of the server as well as inspect errors from the website... also i get 500 internal server error when trying to initiate chat feature of the website and the apps crash also for the apps sometimes it crashes on launch... you can check the website here [login to view URL] to be clear I want to fix everything website and apps bot IOS and Android.. and the issue clearly is from the server side as the apps and website were working fine before migrating to digitalocean... I think it's a permission issue..
