Download failed (status code 520): failed to parse JSON response: Unexpected character (<) at ?:1
I have tried both steam version and official version of factorio, this error still occurs from time to time.
In the worst situation, I need to reconnect over 20 times to join a server.

I probably couldn’t help in diagnosing this, but for anyone that could, I believe having a log file that shows the error as well as information on if this is always the same server, different servers, or all servers would be helpful.
