Can't connect to Web Page on GL-MT6000(Flint 2)

Routers
1

I am unable to authenticate to the admin web page. The router is working like it should and I am able to ssh, it's just the web page.

When I get to the web page I put in my password and I get the following error...

Unknown error occurred. Please check the network environment or reboot the device.

I ssh'd into the router and reviewd the contents of /var/log/nginx/error.log...

I am on the latest firmware. I tried to reboot a few times

2

Did you modify anything?
Which exactly firmware version are you running?

3

I did a bunch of modifications to my settings but nothing on the nginx configuration.

I am on V4.5.8

4

If you are totally sure you did not change the nginx config, you can try to restore the original one:

/etc/init.d/nginx stop
cp -R /rom/etc/nginx /etc/nginx
/etc/init.d/nginx start

Should restore the original one.

Oh, and make sure you did not change something connected to lua on your router. Lua is highly used by all GL applications.

5

I've got the same problem "Unknown error occurred. Please check the network environment or reboot the device."

I didn't change anything lately. It was on 4.5.8 as I recall.

I've did what you wrote:
/etc/init.d/nginx stop
cp -R /rom/etc/nginx /etc/nginx
/etc/init.d/nginx start

but it didn't help.

got the same errors as the OP:

Well, I've did update to 4.6.0 beta2 from LuCi and now it's OK but in the:
/var/log/nginx/error.log every few seconds I do get:

and the file is growing up

It seems you changed something in LUA. That is really problematic.

I think you should run:

firstboot

This should revert problems

8

I ended up doing a hardware reset on my router and it's been good since.

I think my specific problem may have been a result of me doing opkg upgrades in the underlying OpenWRT OS.

Yup, don't do this - it's not how updating works on GL firmware.
