GRINDR app on Sophos UTM9

Vivek, Thank you so much for your response. I added the exception but I am still having the same problem as before. In the chat it says "Connecting" with a spinning circle and the message does not send. Something is still being blocked. If I turn off WIFI and use data the status "connecting" goes away and the message sends.

Under the advance shell, cd /var/log/http.log check which are the similar urls for the site GRINDR are getting blocked, based on that log, we can create a regex url and add it under the exception list.

Few more regex can be added:
^https?://([A-Za-z0-9.-]*\.)? web\.grindr\.com\.cdn\.cloudflare\.net/
^https?://([A-Za-z0-9.-]*\.)?app\.grindr\.com/

Additionally, you can trying adding the DST IPs, Under Web Protection > Filtering options > Misc > Transparent Mode Skiplist > Skip Transparent Mode Destination Hosts/Nets:

IPs:
> 104.16.235.5
>  75.2.70.75
>  99.83.190.102
> 13.227.138.2
> 13.227.138.41
> 13.227.138.43
> 13.227.138.34

I did login on the console to view the http.log as you suggested but I didn't see the device listed in that log at all with any blocked messages.
