3850 Catalyst GUI Timeout

[Elnook]

Hi,

I downgraded to 16.3.9 on a 3850 for a lab environment as I want to use for its AP capabilities,  as soon as I log into the GUI it gives me "Your session has timed out, please log in again"

Any suggestions?

start with some basic checks, make sure http and https services are configured and web auth is set to local with priv 15 credentials.

switch# configure terminal
switch(config)# ip http server
switch(config)# ip http secure-server
!
switch# configure terminal
switch(config)# username your_username privilege 15 secret your_password
!
switch(config)# ip http authentication local
