16:32:09 FATAL: Opening lock port: listen tcp 127.0.0.1:0: bind: cannot assign requested address

Hi

I installed on one of my laptops and this is the message I am getting. I am running it via terminal on Debian 64.

I get it, the port is locked by why?

When I ran it the first time, it ran but I could not connect to 127.0.0.1:8080. It said the web server is running but the page was not loading so I killed the process and restarted, now that is all I get. And no syncthing is running anywhere.

thanks

That error looks like it can’t open a listening port on any port (:0 is to ask the system to assign a free one). In other words, that’s really weird. Don’t you have a 127.0.0.1 address on your system?

I have no idea why it is throwing that error now ;( The port is not block, it looks like it is prematurely exiting for some reason to me.

Really bizarre. I ifconfig lo down and ifconfig lo up. Now it works ;(

This is the operating system refusing to let syncthing open a port on the lo interface, so there’s something weird there.

Edit; Ah, I see you solved it.
