I have been running into an intermittent problem on multiple Asus Routers, all running Asus Merlin Ver 384.17. About once every couple of weeks, the router gets into a state where I can no longer log in the the GUI interface. When I try to login, I get the username / password window, but then just a blank screen that eventually times out. Once this happens, I can't even get the logon screen.

While the router is in this state, it seems to still be fully functional. Data is still routed correctly. In addition, I can connect OpenVPN clients to the router's VPN Server. However, I have no way to control the router, unless I have someone at the physical location reboot the router by powering it down.

HELP!!!

If you can SSH through to the Router when this happens ... issue the following command ...
Code:
service restart_httpd

I'm not familiar with SSH. How do I do that?
Go to the Administration Tab under the webui and select the "System" tab from the top selections - scroll down and enable SSH from the LAN only.
Then use Putty to connect to the router using the SSH protocol on port 22.

If you have to do this from a remote location - then I would recommend that you setup the OpenVPN server on each site and VPN through to the Router network to carry out SSH sessions. Do NOT ever open webui or SSH to the internet.

What routers is this happening with?

I might add, I get no login screen...

I just type in 192.168.1.15 and nothing happens.
But it works fine!
Are you by any chance running unbound?

My RT-AC86U on 384.17 and on 384.18-a1 suffers intermittently with this problem - but only if I have unbound installed.

He is a really funny thing...
So 192.168.1.15 GUI is not accessible via any wifi device, but on the LAN I can get the login screen to access the GUI. strange it is. But like I said, it works fine.

I’ve also noticed with 384.17 the WAN configuration page (but no others) doesn’t always load properly (using MS Edge Chromium browser). One or more page refreshes or browser back and then forward fixes it. I’ve not seen an issue with the login page. Maybe be related, however.

I have similar issue. Using AX88U since six months ago always with latest stable Merlin's FW, currently 384.17. It started about few weeks ago. The configuration is as following:

1. AiProtection is OFF
2. AiCloud is OFF
3. Two OpenVPN servers (one TCP and one UDP) with TAP interface running
4. No AiMesh
5. Alexa & IFTTT OFF
6. Media servers OFF
7. Samba ON, FTP & NFS OFF
8. IPv6 OFF
9. Scripts: amtm, unbound Manager, nsrum, ntpMerlin, scMerlin, spdMerlin.

Network: 2 wired PCs (one Windows 10 and one Linux Mint); 3 wired/wireless laptops (Windows 10); 2 Android smartphones; one wired NAS (XigmaNAS OS, based on FreeBSD 12.1); one Ubuntu Server 18.04.4 LTS VM running OpenVPN server and CUPS Print Server as a guest under XigmaNAS (VirtualBox).

The XigmaNAS box is running also Transmission daemon normally managed through Transmission RemoteGUI from one of the Windows 10 laptops.

About two weeks ago I started to have problems with reaching router's WebGUI, transmission control via Transmission RemoteGUI, access to XigmaNAS WebGUI, general problems with Internet access. Restarting the router's http daemon via SSH didn't help. Rebooting the router fixed the problem. Two days ago it happened again and rebooting the router fixed the problem.

I am suspicious that the reason is exhausting the connections managed by the router, but cannot be sure. The Transmission daemon running on XigmaNAS box is using DHT, which results in many unreplied UDP connections and may lead to exhausting the connections, but no prove for that. No any indications in the router's syslog so far.

My router's GUI is not accessible again. I logged into SSH with PUTTY. I successfully entered the username and password. I then got "
ASUSWRT-Merlin RT-AC88U 384.17_0 Sun Apr 26 02:26:32 UTC 2020", but I never got a prompt to enter a command.

Rebooting does get me temporary access to the GUI. But for a limited time.

I'm having a similar problem with my AX88U running Merlin 384.17. I can access the GUI interface using my iPhone SE-2020, but I cannot with my PC, which is on Windows 10 2004.

Any ideas?

Additional Note: I can access the GUI using my wife's PC, which has the same version of Windows, too.

I have just started seeing this issue on the latest 384.18 alpha but I have never seen this issue before with 384.17 or earlier and also not seen this with the earlier 384.18 alpha builds.

So I am hoping that re-flashing the latest firmware will fix it (using the dirty upgrade process).

I am also having this issue of logging into the GUI with 384.17 on a RT86U

happens every day or so, and never had it on previous firmwares.

Reboot ( Power off and on ) brings it back but is a bit of a PITA !

Anyone any clues as to why or how to resolve ?
