I've been running a Godot client/server pair for some time now without problem, however recently whenever an HTM5 browser client attempts to connect to the server, the server throws "mbedtls error: returned -0x7780". Not only that, but the client does not show any error, it seems to just hang attempting to connect.
This only occurs in an HTM5 client in a browser, running the client as a standalone can connect fine. Any suggestions as to how to go about debugging this would be great. Like I said, up until recently my setup was working fine, and I haven't changed anything; it just stopped working all of a sudden.
