Steps to try in the following order:
- Make sure you can ping the router.
- Clear the browser cache.
- Try another browser.
- Try another computer.
- Reboot the router.
- Router back to factory defaults and configure it manual again.
From Chrome browser:An exact error msg or more detailed description of what "could no longer access the web interface" means could be helpful, especially since you said the web server is running.
Can you SSH in and remove the cert?
Also, using ssh and ps, I don't see any process running that I can identify as a web server. I thought maybe nginx was being used. Anyone know what process is the server (and possibly how to restart properly from ssh, if reboot does not restart it?)"This site can't be reach. <IP address> refused to connect."
I did not make changes to the LAN port settings. IIRC, the http (not secure) LAN port 80 access was removed in an update some time ago, with only https supported, and it was defaulted to 8443 as you say (I've tried 80, 443 and 8443 with the same results - no response from server)You haven't altered the 'HTTP LAN port' setting on the Administration->System page, have you? This, of course, defaults to 80, but if you've unintentionally altered this, then you need to use the new port.
Have you tried https on port 443 or 8443?
How about running a port scan on the router to see whether any other ports are open?

Hi, everyone!!!Aha! - I found something in syslog:
This makes sense as it appears something is wrong the the key/cert I tried to update, or the code that reads and installs it. This was the last operation I performed using the web interface before it became non-functional.
Any ideas on how to remove the (presumed bad) cert and restart httpd?
That's is a well known issue. AC88U is one of garbage routers.I was updating my cert (Let's Encrypt - need to do it manually since my ISP blocks port 80) and after reboot, I could no longer access the web interface. The router is working, but I can't access any settings.
Any idea what this might be? I can ssh in if that will help.
What would you recommend as a not-garbage router?That's is a well known issue. AC88U is one of garbage routers.
Solution: Factory Default.
I met just the same problem on my AC86U today, and it took me 3 hours to find any clues to fix. Fortunately, I read your post, and it did work. Thanks a lot!Hi,
I've a good news.
I resolved with these commands:
nvram set http_enable=0 save commit
nvram set https_enable=0 save commit
nvram set https_crt_save=0 save commit
service restart_httpd
Enjoy
I have still not solved my problem. I did determine that a corrupted cert was causing httpd to fail, restart, fail... etc. I was able to ssh and replace the certificate with a valid one. However, the root/intermediate certificates are expired, and I've found no way to replace them. Asus support is less than useless -- it's actually negative help, taking up my time explaining the same thing multiple times, only to receive a standard (useless) response (to a question I've not asked and a problem I don't have).I met just the same problem on my AC86U today, and it took me 3 hours to find any clues to fix.

Isn't this *dis*abling both http & https support (and certificates) and saving to nvram? I'm not sure what it even means to then restart httpd.umberto.agosto said:
