Qtox: tox does not connect/ go online any more

[Itoxu]

Brief Description

qTox version: v1.16.3
Commit hash: https://github.com/qTox/qTox/commit/8eed684c37bd711de2ca4bd863f5f0509edcdc2d
toxcore: 0.2.3
Qt: 5.9.6
System: Windows 7

Reproducible: Always :
tox used to go online a couple of seconds after starting the program, indicating a green dot next to user name on top of screen.
For about 2 weeks now I cannot get the green dot, online status any more. Program starts but stays offline, indicated by grey circle instead of green dot. Cannot receive messages from or send messages to other users.
Everything worked fine until about 2 weeks ago. Used to run tox several times per week.

Steps to reproduce

1. start tox
2. wait for program to open
3. wait for online status to be indicated by green dot

Observed Behavior: no green dot, remains grey circle instead (offline)

Expected Behavior: green dot, online status

Cannot find any answer in previous threads and would appreciate a guideline how to solve the issue.
Already tried to reinstall program.
Tox does work though when I use a different account when starting Windows. But then I cannot access my original profile and chat history etc.

Could you provide a debug log after 30 seconds or so of failing to connect? You can retrieve it from the advanced tab under settings.

Can you also try a newer build from here: https://github.com/qTox/qTox-nightly-releases/releases but make sure to backup your profile directory!

Proxy settings are saved per-profile which might explain why it only doesn't work on your one profile. Do you have an invalid proxy set under settings -> advanced?

I have not changed anything, ever.
My guess is that it has to do with a recent W7 update.

yesterday I downloaded tox again from the tox.chat website and installed it over the existing prg. Nothing changed though. Maybe I need to uninstall the old version first, but I don´t want to loose my profile. How can I save that?

I have not changed anything, ever.

There was a bug in an old version https://github.com/qTox/qTox/issues/5311 that incorrectly set an invalid proxy option. Your client is only trying to connect to TCP relays, not connect over UDP to bootstrap nodes. This would happen if a proxy is set.

Please check that "Proxy type" has "None" selected and that UDP is enabled (both are default):

but I don´t want to loose my profile. How can I save that?

your profile (Tox ID, friends list) are stored in %APPDATA%/Roaming/tox/profile.tox, your chat history at %APPDATA%/Roaming/tox/profile.db, your profile client settings at %APPDATA%/Roaming/tox/profile.ini and your global client settings at %APPDATA%/Roaming/tox/qtox.ini. Backing those files up, or just copying the whole tox/ config dir, will make sure nothing is lost.

Thanks a lot! Problem solved.
Setting the proxy type to "none" was essential. Before that I could not select the UDP option, as it appeared gray and could not be clicked.
My tox is now connecting online again.
Thanks everyone for your help!
