Mine has just started having this problem about 10 minutes ago on my only account. All internet connectivity is fine. I can log into buddyauth.com without issue and I have double and triple checked my key - that's not the problem. About to try the suggested fix above and will report back after that.
Same thing here. I hope it'll be fixed soon. Btw I ran the bot 48 hours without even monitoring it 1 second, and it worked w/o disconnect or crashes, so it's way better than it used to be, thanks )
