LogMeIn Desktop Client is not allowing anyone in the org to get to credentials screen on windows domain joined laptop. I reviewed the logs of the application and received this error:

Hey @GlennD

I received further information from the companies domain admin and they informed me that they are enforcing a GPO that TLS 1.2 is being used for company domain computers. Is there any information you can provide regarding the Logmein Desktop client and what TLS version is being used for the online services for the application? Thank you

GlennD

I am checking with our team regarding the domain settings.

Tried connecting to a different WIFI still same error.

Flush DNS via CMD, still same result.

Network team has reviewed that allowlist KB article last week and made necessary changes.

I removed the computer from the organizations domain and I was able to get the LMI desktop client to work.

Question is what would be controlled within the domain settings of the organization would be causing the error?

Thank you. As this error is a result of a connection issue there are a few more things we can check:

Try connecting over a different network connection. Since this is a laptop can you connect it to a different WiFi network to see if you get the same result? If your phone supports it you could create a temporary hotspot to connect to to run the test. If you are able to connect successfully we will know the issue is network related and direct our troubleshooting there.
Reset you TCP/IP settings and Flush/renew the DNS on the laptop.
Check your Firewall settings

Those settings were already checked on my computer internet options settings:

Hi @Mlukay, welcome to the community.

When I have see error 12031 before, it was related to the TLS encryption settings of the computer.

In Windows:

1. Open the Control Panel
2. Click Internet Options
3. Click the Advanced tab
4. Scroll down to the Security section
5. Check the boxes next to Use TLS 1.0, Use TLS 1.1, and Use TLS 1.2
6. Click Apply
7. Click OK
