Yesterday some users reported that they could not enter the Grindr version for PC.
After checking that rumor and verifying that it is true, I was encouraged to write this article to give you some tips and you can login.

The first step is to check if the chat service for pc is still down and we keep getting “Grindr Web 503 Service Temporarily Unavailable”
-If the problem continues, what you should do is delete Web.grindr.com cookies .
-The other option is to enter from another internet server (for example from starbucks wifi) and check if you could access to Grindr online.
If it still does not allow you to access go direct to Sign Up – Grindr Web Chat (grindrpc.com)

Update: Grindr reply my email : Hey Guys, We are under going some maintenance since Nov 2020 , we will be firing on all cylinders again soon. Thanks for your patience! Stay tuned for an update or go to grindrpc.com
