NSS upstream definitely supports ECDHE for a long time. RedHat for years until late 2014 removed (all variants of) ECC from their builds of crypto packages (AFAIK all, definitely OpenSSL NSS OpenJDK) for vague 'legal' reasons, which above I called 'long denial'. I'm guessing when they put it back they made some probably-minor mistake affecting this curl/NSS case. Schannel returns the following error messages when the corresponding alert is received from the Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols. Summary: Offer to re-enable TLS 1.0 on PROTOCOLVERSIONERROR → Offer to re-enable TLS 1.0 on SSLERRORPROTOCOLVERSIONALERT Johann Hofmann :johannh Comment 3. (Error code: sslerrorprotocolversionalert) The right port for the google SSL is 993. This is a must fix.

Err Ssl Protocol Error Chrome
Which TLS-Version is used on zotero?
What Is Ssl Protocol Error
- Zotero is currently based on Firefox 60 ESR and supports everything that supported — TLS 1.0 through 1.3 (though technically a draft version of 1.3).
- Ok, thank you. I want to sync to my nextcloud webdav. It seems there is some kind of problem with my ssl. I use a namecheap-ssl. What could i try to fix this error?
- We can’t help debug third-party WebDAV servers, sorry.
- Hello incoggnito! I had the same problem. Turns out I had disabled TLS1.2 in my apache configuration for nextcloud. Maybe, the draft version of TLS1.3 that zotero/firefox uses doesn't really work with all certificates. After allowing TLS1.2 certificates, zotero is now able to connect and sync. I hope that helps!
