SG3100 Can't connect to www.columbia.edu
Looking for a sanity check here. Can anyone with an SG3100 try to connect https://www.columbia.edu ?
Not sure but all of a sudden it doesn't appear to work though the associated IP pings fine, I get hung at performing TLS Handshake.
Wireshark shows a bunch of retransmits and a RST from the server
I tried changing the MTU and MSS. Also turned off HW offloading.
Can Anyone give me some ideas about what to do next beside contact the Admin over at the website? Or can anyone reproduce?
Checked with my SG1100 with Cloudflare DNS (188.8.131.52) and it loads fine. Also tested here: https://downforeveryoneorjustme.com/ and all is good.
@iith096 thanks guys.
Works fine through an SG-3100 here. Though it resolves to 184.108.40.206 as the main IP for me.
