i'm unable to assist you with these errors, but are you able to share the past and new offers with the Tor community? we'd love to run more exit relays and help mediate the situation with the former provider to ensure that more relays can be run on their networks.
I already updated the wiki about the past. With the new I'll wait till I got some relyable experience how they deal with exit node. shouldn't take to long, today came the first abuse message.
