@svk This issue is not just with openledger.
In another test wallet I am experiencing the exact same issue straight out of the graphene depo.
It was driving me crazy trying to figure out why everything was working and then suddenly didn't.
Perhaps our issue is not identical.. but in analyzing the logs, it appears when account registrations are attempted they are not even posting to the web server. I get no data whatsoever to show that it POST.
Meanwhile all other functions not related to the faucet work just fine.
I hope this is helpful in your debugging.
