WebGUI not accessible for more than 2 hours ( No response from Syncthing after unpausing a folder + restart )

Hi,

I only found this informative, but not helping post: reason for: … has mismatching index ID for us (somehex != someotherhex) …

I’ve unpaused Folder-A at :mantelpiece_clock:17:12 and then restarted Syncthing on my Win7 machine via the WebGui and left the office for $food.

(The Syncthing v1.1.4 service was running and restarted by me a few times the last days with without trouble.)

Now, about 2 hours later, I can’t access the WebGui anymore, though syncthing.exe is started and running (as far as I can see in Windows Taskmanager)

This is, what the log says:

It seems to be stopped a :mantelpiece_clock:17:21:51

When I check via the WebGui from my Mac, it says, that the Windows Remote Device is disconnected.

Now the question: Is restarting Syncthing on my Windows machine (aka killing via Taskmanager) the only option, I have? (Beside waiting and hoping for the best!)

Ha! of course, something changed, as soon as I wrote this post.

So now, I can see that the windows machine is synching with another device, but the WebGui is still not accessible.

The log shows normal activity.

Some hours later and still no WebGui visible/accessible.

The Log shows tiny movements, so Syncthing is working anyhow…

No progess in Syncing to a Remote Device, which is working and ready to receive all the files (191GiB).

I’ll wait until tomorrow and then, I guess, I need to kill syncthing.exe, unfortunately, if no WebGui appears. Maybe a good idea to delete the Database folder… Lets see what happens.

Just in case, here is my config.xml with stripped folder and device ids.
