Hi Erisa!
Thank you for your reply. We have tried the Worker Route method you suggested but it results in the exact same issue (522 error). We removed the Custom Domain, made sure that the WORKER DNS record did not exist anymore, added a fake proxied fallback A record to 192.0.0.1 and added Worker Routes for domain.com/* as well as *.domain.com/* pointing to the hello world worker.
I can share the domain name but would like to not do so publicly. Can I DM you somehow or reach you by email?
There are actually two IDN Custom Domains set as triggers for this Worker and one seems perpetually stuck in “Initializing” while the other switched to “Active”. Both result in the same errors though.
The other bug for the Custom Domain in Pages can be easily reproduced with any kind of IDN btw. Try for example to enter €.com and you will see the dashboard claims it’s an invalid domain.
Again thank you for your help.
