Dnscrypt-proxy: dnscrypt keep shutting down

[elmakong]

when i check the log (windows 10 x64) i keep getting this message

The DNSCrypt client proxy service terminated unexpectedly. It has done this 3 time(s).

whats wrong?

[elmakong]

is it possible because the load balancing flag lb_strategy = 'fastest' was set? because when i try to comment that line, it doesn't seem to be crashing anymore

[iWARR]

I have lb_strategy = 'fastest' on Win8.1 and everything is fine.

Also notice this https://github.com/jedisct1/dnscrypt-proxy/issues/454 tip.
Looks like Win7 have less copatibility with the rescent versions. This OS is too obsolete today, as well.
But Win8/8.1/Win10 are more "close" versions, instead of Win7/Win10 comparison.

[elmakong]

i dont use win7 anymore..also, the problem is not "service wont start"...it will start, but after some time, it just shut down by itself.

Confirming that setting fastest in lb_strategy causes service to die - Windows 10 x64 LTSB

I have the same issue - service is dying out on Windows Server 2016

[jedisct1]

Unless someone has a solution, or a relevant stack trace, or a reliable way to reproduce this, we can't expect this to be solved.

@jedisct1 How debugging mode or logs can be enabled on Windows?

Can it run in console mode instead of a background service?

[jedisct1]

Run it from the Powershell console, just by typing:

dnscrypt-proxy

And don't close the Window.

[DRSDavidSoft]

@jedisct1 Quick question though, does it matter if it's ran from Cmd.exe or Powershell.exe?

[jedisct1]

I haven't used cmd.exe for a long time, but It shouldn't matter at all.

You can copy the following codes into Notepad, then save as dnscrypt-proxy.bat, put alongside the main program, then it would reproduce if you double click this batch file.

@set @_cmd=1 /*
@echo off

@CD /d %~dp0
dnscrypt-proxy -config dnscrypt-proxy.toml

[DRSDavidSoft]

@KrasnayaPloshchad Interesting, I always used cd /d %0\.. to switch to the current directory. Out of curiosity, what does @set @_cmd=1 /* do? And why not put @echo off in the beginning?

BTW, I currently do it with a shortcut (.lnk file) rather than batch scripts.

@jedisct1 I haven't captured the service dying out yet. I'll post a new comment when it happens.

[KrasnayaPloshchad]

OK, I dropped @set @_cmd=1 /* and @echo off in the beginning, but this problem still affect me sometimes.

[B00ze64]

@DRSDavidSoft @set @_cmd=1 /* is used in the default proxy scripts to hide the batch commands from the javascript call to cscript, when re-running the script to gain admin privileges. Neat trick.

[DRSDavidSoft]

@B00ze64 Wow, that seems interesting. Not to get carried away, but what is cscript doing here, and how does this workaround work to elevate the script? I'm eager to know!

I have the same problem. I'm running it on centos(x86) and debian(arm), it just can not keep running for more than half a hour, no error messages. However one time I got the flowing stacktrace, hope that's helpful.

Thanks for the backtrace!

I think that was fixed by a1c8012fc62c2a0998a96c298addfce896aa2329
