Guessing wildly - so somehow the TLS library increased the minimum standards, and requires longer DH primes, probably 1024.
Yes, guessed that, but so far I fail finding how to override it. Will continue tomorrow, I have some nightwork to do now :)
I know this is a cop-out, but maybe contact university IT support and ask them?
Yep, also tomorrow. Guess others will fall across that, too, sooner or later. Thanks again!
first hit search for mutt tls prime length is http://www.mutt.org/doc/manual/ and searching it for prime immediately finds 3.362. ssl_min_dh_prime_bits Type: number Default: 0 This variable specifies the minimum acceptable prime size (in bits) for use in any Diffie-Hellman key exchange. A value of 0 will use the default from the GNUTLS library. (GnuTLS only) which would suggest setting an explicit value there. second hit for gnutls prime length is https://gnutls.org/faq.html and the first FAQ is a suggested workaround
