I just went through troubleshooting this error and from reading many threads about it, I think multiple scenarios can cause it.

In my case, the problem was that I was launching GOG Galaxy via RDP. When launching GOG via my Windows 10 laptop console, the error didn't occur.

Interestingly, if I launch GOG Galaxy via the console, then close it, and relaunch via RDP, the error doesn't occur....this behavior persists until a reboot.

yup! I had the same issue. Drove me nuts! Connecting from my PC directly rather than a terminal window works fine and dandy! Thank you!!! :-) :-)

Same issue as everyone else. Using Os X. Doesn't work at all. What a joke

Please contact our support team about the issue so we can investigate it deeper and learn the scale of this problem :)

I also experience the same issue when launching via RDP. Not sure what that was about, and Galaxy continues to work fine if I ignore that warning

Why does the loss of connection to GOG service warrant shutting down Galaxy anyway?

Steps That Worked For Me on Win10.

Testing Process:
- Turned off firewall, GOG installer worked.
- So turned it back on and it didn't again.

Solution Process:
- Control Panel\All Control Panel Items\Windows Defender Firewall\Allowed apps
- Added C:\Program Files (x86)\GOG Galaxy\GalaxyClient.exe AND GalaxyClientService.exe

Worked with firewall turned on after that. :)

I faced the same issue and tried to add firewall exceptions for GalaxyClient.exe and GalaxyClientService.exe (I don't see the point since normally, Windows prompts automatically to allow or block when a port opening is requested for the first time) but problem persisted.

I tried to launch these commands in an admin prompt :
net stop winnat
net start winnat

Then I can launch Gog Galaxy, wait few minutes without the "Communication Service was lost" message.
No need to disable hyper-v or reboot Windows.

Too bad I didn't try first this command first before restarting winnat service :
netsh interface ipv4 show excludedportrange protocol=tcp
to check if some ports where locked

It looks very similar to this problem with other softwares (like IntelliJ) from JetBrains company that made me think to try this winnat restart solution when seeing some people's posts about hyper v deactivation to solve the issue : IDEA-238995 (links are blocked right now...)

Too bad the gog galaxy message is too generic enough "Communication Service was lost" and not accurate enough like port <port number> is already used or something like that can help to better understand the root cause and google it for a solution.

This is awful, I'm not even able to file a bug report because it constantly crashes. It's been like this a year ago as well - how long will it take for them to fix this?
Posted June 11, 2021
They'll fix it when it affects someone important. Perhaps if you were chinese...

evizcerh8: tried everything including firewall exceptions, uninstalling. disabling hyper v worked.
Have this problem today after an update.
If True, I guess gog gets curbed. I have to have hyper-v.

I also had this issue and was searching for a fix. Well I couldn't find any so I went and figured it out myself. I tried uninstalling, firewall allowances, and starting the app in various ways. None of this worked. Well what I wound up doing was downloading Revo Uninstaller (the free edition), uninstalled using the app, ran the advanced scan option after the uninstall was done, made sure to select everything the scan found, deleted the selections, then selected everything in the next window as well, and deleted this also. Afterwards I ran a fresh install. Issue was gone.

It seems doing a normal uninstall leaves a ton of files and settings on your computer. Not sure which file or setting is the root of the issue but this insured a true clean install could happen. I'm positive this issue is the result of updating the app though. Let me know if this helps!

Alright, this worked for me:

Press WIN + R

Run: services.msc

Then locate GalaxyClientService and GalaxyCommunication

Double click each, then change Startup type to "Automatic" for each one, then select OK.
Hope it works for you, too.

Thank you! Had this problem and tried a couple of things then gave up. This worked!

Haven't had a chance to test this yet, but love the detailed response. Definitely agree there should at least be an option to display detailed error message info... Will help the more tech focused of us to actually troubleshoot much easier (which will also help Dev's, hopefully, address the issue)
