When I first established my TailScale Account and added my Cell Phone plus my Synolgy NAS running DSM 7.0.1-42218 all was well. Subsequent I removed my iPhone and NAS from my TailScale network. Today I attempted to add back my Phone and the NAS … The Phone added in without issue but I am not able to add back my NAS, When I run my Synology TailScale App I get the login screen but nothing happens when I attempt to log it in except the following message:
Failed to log in: Failed to fetch
I tried to uninstal and reinstall the TailScale Synology app but the login still failed to work … is there a solution to this please. Thank You.
I just tried that and the package uninstall function of Synology already deletes that folder.
I am having the same issue. The first time I installed Tailscale on two of my synology devices, it worked perfectly fine, but after uninstalling and re-installing, now the login in button does nothing. I am not going to reset my nas devices so I am looking for a workaround.
Thanks for this Jay, this is really useful. I’ve had the same issue surrounding installing Tailscale on my synology. I have deleted all the folders you have listed and I will test to see if Tailscale can be installed brand new again.
So I can confirm that I have got mine to work correctly again after following the command and deleting the following folders recommended. I am using DSM 7 and now it work prefectly again.
I made an account here to share with everyone how I solved this issue. I was getting the same error and spent an evening trying to figure this out lol.
First, SSH’d into your Synology
Then run the command ‘sudo tailscale up’. Terminal then returns a custom URL which I was able to paste into my browser where I was allowed to log into my Tailscale account. From there everything was authenticated and is now running as it should on my Synology.
