It looks like the servers listed in the bug description require SIGN-RSA-SHA384, which gnutls26 doesn't support.
The issue can be reproduced with gnutls28 by disabling the additional signature algorithms:
gnutls-cli --priority "NORMAL:-SIGN-ECDSA-SHA256:-SIGN-RSA-SHA384:-SIGN-ECDSA-SHA384:-SIGN-RSA-SHA512:-SIGN-ECDSA-SHA512:-SIGN-RSA-SHA224:-SIGN-DSA-SHA224:-SIGN-ECDSA-SHA224:-SIGN-ECDSA-SHA1" -d 256 sequencewiz.com
Fixing this likely requires at least the following commit to be backported:
