HybridVPN on XR450 no longer loading


Recommended Posts

I'm having an issue with the Hybrid VPN loading.  It was working for many months and then all of a sudden does not load.  I tried rebooting the router and it does not load on reboot.  Any tips on getting it working again?  Thanks!

Hi Warner,

I don't have an issue with the router not able to connect to my VPN provider.  I'm saying the HybridVPN Rapp is not loading.  I feel like your response is a canned response that doesn't apply to my situation.  Here are some screenshots from my router when I try to access HybridVPN Rapp and also showing 0bytes under Installed Rapps.   Not sure why all of a sudden it stopped working, and not sure of how to get it to load back up.  Tried rebooting, I can try reflashing to see if that will help but wanted to see if there is any other steps I can try first.

You can ignore them, they were a spammer. 

Go to the System Information page and then in the Rapp panel menu ≡ change the retries to 5, reboot from the interface, wait 4 minutes before accessing and see if it works then please.

Unfortunately increasing the retries had no effect.  Should I try something more drastic like using the factory reset button on the router or reflashing the bios?  If so, think its okay to save the settings file to reappy afterward?

A factory reset would likely work but it's not a good idea to make a save file while you have an issue and restore it afterwards as you may restore the issue. If you have a file from this firmware version prior to the issue then you could restore it - not every setting is saved though.

Router is bricked after trying a factory reset.  Trying to access the web interface says "DumaOS is not loaded".  Responds to ping requests, DHCP is active but thats about it.  Tried resetting power a few times and a few more tries to factory reset with no success.  Is there a procedure to reflash bios via TFTP or similar method to bring it back to life?

So my router was unresponsive today less than 2 months since I last reflashed it.  After a long power cycle was still unresponsive but at least the reset button worked and didn't need to reflash to get it back up.  Loaded up the backup config and was up relatively quickly, however i'm concerned on what could cause this as I would expect a production device to maybe need a power reset but not a reflash or factory reset.  I was looking for a setting i've seen on other routers that would reboot on a nightly schedule as that sometimes can help but I didn't see that option anywhere. 

Hybrid VPN didn't load up again, tried increase the retries to 5 but that didn't change anything.  Here is a snippit from the log explaining the error:

Any idea whats going on?  Is this bios still in development?  Do I need to reflash again?  Should I try a reload of settings file?  Maybe a settings file prior to configuring VPN?  I really like this DumaOS and don't want to switch to another router so would really like it to be better!  Thanks!

Did you reboot the router with HVPN enabled by any chance as I think that could have caused it. In which case, make sure to disable first before rebooting and it should be stable. It is still a beta firmware so there will be some bugs.

Yes, unfortunately I think that the config file I saved had the HVPN enabled...  I suppose there's not a way to disable the HVPN before it reboots since it seems like the router reboots once the config file is loaded?

No there isn't, the router shouldn't be rebooting after you enter a config into the router, is that what you're saying happens?

OK, sorry for the delay in response but went out of town for a bit and this was put on hold.  But yes, when I load the config file, the router seems to reboot.  I lose connectivity to the router and when reconnected I checked the logs and it looks like all the rapps are loading like during a reboot.  Luckily I do have an older config I saved prior to configuring the hVPN, so I checked when that when I load the old config I can get to the hVPN screen.  Tried loading the newer config file again just to check if I can get to the screen and disable it before reboot and verified that I couldn't.  I guess I'll try and be careful to turn of the hVPN before saving a new config file.

If you look at the uptime on the router does that show that it has just been rebooted? I would be surprised if it is rebooting and wasn't just a disconnect/reconnect to the VPN

Oh I see, thank you, all this talk on configs I misunderstood which you were referring to - if you upload a router config it will reboot the router with your then previously saved settings, this is normal. If you upload the config captured when you had that VPN issue then yes restoring that config could then bring the issue back so it would be best to resolve the issue, setup everything then download a fresh config. Also I would not recommend restoring a config captured from a different firmware version.

ok, i thought you were saying something about it not rebooting when you load a config into the router.  did you mean after flashing the router or what config were you referring to?  the config i was loading didn't have an issue when i saved it but apparently the hVPN was enabled so since it automatically reboots after loading it, it will thus have an issue once loaded.  i guess i'll have to make sure to create several config files just in case.  is there a way for the firmware to prevent creating the config file if the hVPN is enabled?

I thought you meant that putting a vpn config into the VPN feature was causing you to reboot.

No way to do that unfortunately
