Can't remote follow from new instance
I've got an instance I just set up, based off develop, at https://pl.firechicken.net. For the most part everything seems to be working fine but I get problems when trying to remote follow users on other instances.
This page is completely empty for me https://pl.firechicken.net/ostatus_subscribe?acct=https://shitposter.club/users/Moon
Here's the logs:
