Solved: SG200-26 Web Interface Inaccessible from Chrome After Upgrade to 1.4.11.02

dtheese · ‎10-20-2019

After upgrading my SG200-26 switch to 1.4.11.02, I can no longer access it from Chrome (version 77.0.3865.120).

I have cleared the cache, history, etc from my browser. I have rebooted both the switch and the computer I am trying to access it from.

The only browser extension I have installed is uBlock Origin. I have added the FQDN that's assigned to the SG200-26 to this extension's whitelist.

Is this a known issue? Any suggestions on how to recover without doing a factory reset?

Hello,

I'm seeing similar issues on the SG300 switches after the 1.4.11.02 release upgrade.

In my case I have a wildcard certificate on the switches and am using HTTPS only. I can't access the web interface via the DNS name but can via the IPv4 address (obviously with certificate errors). It's not a name resolution issue- definitely something up on the swtiches.

I've tried reverting to the default cert but that doesn't help either. So doesn't seem to be certificate related.

IPv6 access to the web interface is also broken- but this seems to be a known issue and is listed in the release notes. That may explain why others are not able to reach their web interfaces perhaps.

I agree a factory reset to resolve this isn't a great resolution. It's a big job to rebuild a network of these switches that way....

Kind Regards,

Andy.
