More Info: I found that I could open the sites with Firefox or Chrome intermittently but not IE 10 -
Wireshark screamed about spurious retransmission - encrypted alerts with Firefox but opens the GUI ok
Google says Page unresponsive and pops a message that the page at https:xxx.xxx.xxx.xx is has error getting menu: References Ajax is not defined
Also getting other errors like expected end of input
I do not see any of this behavior when connected directly to the switch - only across subnets
I downgraded to 11.4.4 firmware after seeing that 11.5.0 had been pulled from the available downloads on the Adtran Support site. I am able to access HTTPS from Firefox and IE11 now but Chrome is still not working.
