Guru Maps traffic is blocked on Android while Blokada shows that it's allowed

First I’ve received complains from our users, then reproduced this issue on our device. For tests I’ve used Blokada v5 on POCO F3 Android 12. Fresh install of Blokada and Guru Maps without any customisation. Inside the Guru Maps we use curl for most of internet requests and our main server is Blokada shows requests to our server and says that it’s allowed, however Guru don’t receive responses from server.
When I tap on Guru Maps in Blokada apps list and it’s marked as ‘bypass’ it works correctly. What should we do to solve this issue? I believe that other apps that use curl for web-requests experience same issue too.
