ERR_SSL_PROTOCOL_ERROR since yesterday, no changes made

Problem description:
As of yesterday, on two apps I have hosted on Replit I am seeing SSL cert issues with the error ERR_SSL_PROTOCOL_ERROR. Both apps worked prior to yesterday.

Expected behavior:
The apps should load successfully.

Actual behavior:
I get this error: ERR_SSL_PROTOCOL_ERROR in Chrome

I believe that most Replit machines are okay and should work as normal now.

Best thing now is contacting support at or create a ticket about your Repl at

Hey @ChrisBrownridge!

Can you please send me the links to the Repls that are giving you the SSL errors?
