GS1900-10HP and GS1900-24: No SSL-Connection possible anymore
i'm in posession of a GS1900-10HP and GS1900-24-Switch, which were configured Mid 2018 (bought Q1 2018). Recently i wanted to access their WebUI through https (unfortunately secured only by their self-generated Certificates) to upload the recent Patch-Hotfix based on the current Beta-Firmware. To my surprise, i wasn't able to access the WebUI through https anymore. Through the current Firefox-Version i got the response "SSL_ERROR_NO_CYPHER_OVERLAP", while Chromium told me about "ERR_SSL_VERSION_OR_CIPHER_MISMATCH", so it seems these Zyxel switches uses some kind of outdated SSL-ciphers in securing their https-connection, which none of my current browsers accept. Fortunately i still got access over http (even though i planned of disabling it for security purposes), so i finally could upgrade their firmware with the latest one.
Well i thought, hey maybe something were changed in the last release, especially as they were mentioned in the changelogs that you now can regenerate a ssl-certificate. Unfortunately it didn't help at all in solving these problems, so the symptoms are the same. As i cannot change the https-security profile to something else except the default entry "default", there are no options to try out here.
Are these problems already known and if that's the case, will there be a fix for it (through setting the ssl default ciphers to something current)?
Many thanks in advance and best regards
