Ruckus Access points causing SSL errors

[Kh818]

I have a Rucukus icx-7150 and along with a few R850 access points. Everything was working fine until we switched over from ATT to Spectrum.

Now when connecting to the access points, we receive SSL certificate errors when loading web pages and a lot of apps on our phones do not load. It happens intermittently. The internet will work fine for a few mins then start coughing up these SSL errors after a few mins.

Are we supposed to update the certificates of the switches/access points after switching isps? Or is something on the ISP end causing this to happen?

AFAIK, everything is set up similar (Ethernet cable from router to one of the 12 ports on the 7150). The only difference being the ATT was fiber and the Spectrum is via COAX.

Any advice? I have web and telnet access to the switch (although I haven’t figured how to get into the r850’s yet)
