Hi @simon4, can you let Support know? We saw a few 522s earlier from one of our data centers and I’d like Support to know you hit this as well. If you open a ticket, please share the number here as I’d like to track it.
To contact Cloudflare Customer Support, login & go to https://dash.cloudflare.com/?account=support and select get more help. If you receive an automatic response, please reply back and let them know it’s still an issue.
With that being said, here is a bit of background on 522s in case what you’re seeing is unrelated to the issues we observed earlier, Community Tip - Fixing Error 522: Connection timed out.
