I just updated my SG300-28P to the latest firmware, 1.4.11.2, after previously running 1.4.10.6.
Previous to the update, I could access the Web interface with the hostname I'd specified in System Settings (as part of the FQDN I use for my LAN), i.e. https://switch1.domain.com (where switch1 is the hostname set in System Settings, and the rest is the search domain I use on my LAN).
Following the update, any attempt to access it by hostname results in a long pause whilst it is "waiting for switch1.domain.com", before finally going to a blank page with only the opening <html> tag of the page loading as content if I view the source. Nothing else loads. I can view certificate information so it is obviously getting a response, but grinding to a halt before it gets any further. If I access the Web interface using IP address, it connects fast and without any problem.
Worth mentioning, I can still ping / SSH to the switch using the hostname / FQDN, so I don't think it's a networking issue, just that the Web interface has stopped loading for hostname requests. I've also tried clearing the browser cache and using different browsers on different machines, but it's the same for all.
The switch's logs do not show any connection attempts at all when using hostname but do show successful connects when I use the IP.
Has anyone got any ideas? Thanks!
