I have an 1850 access point . It is working fine as an access point and I can SSH into it no problem, however, I cannot access the web interface using any browse

this problem started before two days ago

before that  I accessed the web interface using any browse

now 

When I connect using https, it prompts me for the username and password and then returns:

This page isn’t working x.x.x.x didn’t send any data.
ERR_EMPTY_RESPONSE

 can anyone helps me please ?

Controller cannot connect to web interface

is the AP acting as Mobility express ? what Logs you see when you try to access web on AP ?

have you tried reboot the AP and check ?

I only think of latest browsers with TLS connection issue or certificate expired.

Try re-generating the certificate? config certificate generate webadmin

You will need a reboot after that.

Then your options are:
- Open a TAC case if you have a Cisco support contract
- Factory default reset the ME and reconfigure it.
