Difficulties connecting to comby.dev

Describe the bug
Safari, Edge and Firefox currently from time to time refuse to connect to comby.dev from Germany with error messages regarding TLS Security.
Safari: Safari cannot establish a secure connection.
Edge: ERR_CONN_CLOSED
Firefox: PR_END_OF_FILE_ERROR
Reproducing
Open a browser and go to comby.dev. If you can connect, navigate around. Sometimes you will get a problem with the connection.
The problem can reliably be reproduced with curl:
Running curl -L https://comby.dev --resolve 'comby.dev:443:2a09:8280:1:0:0:0:f:1705' (connecting to the Amsterdam server) results in curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to comby.dev:443. Running curl -L https://comby.dev --resolve 'comby.dev:443:34.83.23.240' (connecting to the Oregon server) resolves without an issue.
Expected behavior
The site opens reliably.
Additional context
I'm connecting from Germany. Qualys SSL Labs shows the Amsterdam server not having security protocols in place. curl -L comby.dev reports curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to comby.dev:443
Problem has also been verified by other person on other network, but in same town.
Thanks for the context. I'm not able to replicate in browser, but I'll look into the SSL certificate on the site host
I'm seeing this as well - verified from two devices with two browsers (Chrome/macOS and Firefox Focus/iOS).
Think I found the issue and it should be fixed (bad alias in dns records). Please reopen if you run into issues again.
