Hello,
after trying to get SyncThing and SyncTrayzor to use a Socks5-Proxy for about two days, without any success, I hope someone can help me/point me in the right direction. Somehow I can’t find any tutorial on how to do this. The “Using Proxies” chapter in the Docs doesn’t really help for windows at all. I already tried setting a System-wide Environment Variable and I used the field in SyncTrayzor, without success.
I really hope someone can help with that.
Greetings, Glissa

It prints a message in the logs if it finds proxy environment variable, so you could check if its being picked up.

Thanks for the fast reply. As far as I can see, it is not picked up. In the SyncTrayzor settings under “Syncthing Environmental Variables” my config is: proxy\_all=socks5:127.0.0.1:xxxxx; ALL\_PROXY\_NO\_FALLBACK=1
SyncThing should not connect to a network, without the Proxy running, if I understand the function of ALL\_PROXY correctly. It doesn’t matter wether the Proxy is up or down, SyncThing connects to a relay server in both cases, after detecting strict NAT from the firewall. There is nothing in the logs indicating anything about proxy-usage or the IP/Port used/to use.

Syncthing respects proxy settings even when connecting to relays, as in some cases proxy is the only way out. If it’s not, that is why we have the fallback which you are explicitly disabling.
It seems env var you set is invalid as it’s missing slashes, so I wouldn’t be surprised if go just ignores it.

Oh, that is quite embarassing.
After inserting the slashes and double checking everything with the doku, nothing changes. The Log still shows exactly the same lines, only changing the IP-Adresses of the discovery/relay servers.

I suggest you try running syncthing outside of synctrayzor, via cmd, setting the env var before hand in the same shell and see if that works.

You want `all_proxy`, not `proxy_all`.

Thank you both for answering.
I just did as @AudriusButkevicius suggested and started SyncThing via cmd and voila, proxy works.@calmh, yes, I corrected the commands, it did not change anything.
I guess I will write a batchfile to start Syncthing instead of using SyncTrayzor, sadly.
Does it make any difference to write socks or socks5? The Doku has both in it, but at least in SyncTrayzor neither of them seems to do anything. In cmd socks seems to work.
