Web UI died.

[ozzed]

Hi!

Yesterday I was unable to access the web UI on my RT-AC87U. All that came up was a white page. The router was working fine other than that, and I could access it through SSR to enter the reboot command. After the reboot, I could access the web UI again. Is this a general problem with Asus routers or could it be the Merlin firmware? I'm running 380.57 and have had the router for a little over 2 weeks, and this is the first time anything like this has happened.

What FW version? Its a known issue httpd crash, but it shouldnt happen now on latest code.

It's 380.57

Was httpd process still running, even crashed/not responding?

Or it wasnt there anymore? (under ps command)

I didn't check that. I don't know how.. How do I check this if it happens again?

 

[hggomes]

ps | grep httpd

 

[ozzed]

ps | grep httpd

OK, thanks I'll remember to check this if it happens again.

My temps are (In case it could be because of overheating.)
498 2.4GHz
64c 5GHz
73c CPU

They are fine.

49c 2.4GHz (not 498c ah? kk)
64c 5GHz
73c CPU

LOL no I use it as a waffle iron

I meant 48c. But yeah.. Glad they are fine. I haven't been able to find anything about Tmax for any of the SoC's but if they are fine then that's not the issue.

CPU TJMAX is 125Cº, i have posted the datasheet on this forum not sure where now, but its lost in some place here.

You may also try a different browser to see if that might work.

 

[hggomes]

Indeed.

I did. And different client. But I didn't have any luck with that either.

Did a hard reboot (pull the power plug) of the router fix it?

Did the older 378.56_2 firmware also exhibit this issue for you?

Have you tried john9527's or hggomes firmware as a test?

Like I said in the OP I was able to connect with SSH and just type reboot and then the Web UI was back to normal. So it's not like it's a serious thing as of now but if it starts happening again and again it might be. But hopefully it was just a hickup.

If it happens again, try

service restart_httpd

instead of a reboot.

If you see it's happening several times (crashing httpd) try to open a terminal with strace -p PID(httpd), you will know why its happening.

PS: I'm not sure if RMerlin or ASUS Stock FW has strace on it, probably not.
