Negotiating SSL...
SSL connected and negotiated the following cipher:
Key exchange: TLS_AES_256_GCM_SHA384, 2048 bits
Data encryption: TLS_AES_256_GCM_SHA384, 256 bits

Host SSL certificate verified.
Certificate issued to computer: *.lmi-app22-01.logmein.com
Certificate issued by: GlobalSign RSA OV SSL CA 2018

Connection failed.

 

How can we solve this?

    Hi Arai , 

    Connectivity issues can be related to:

    • Network being choppy - Please run a trace route to secure.logmein.com on the host machine's Command Line and a continuous ping also.
    • ISP (internet service provider) may be down - Please check with your local provider
    • AV/ Firewall - Verify on your host machine if the connection is being blocked by a firewall or Antivirus.

    Also, on the host computer, if you have set Debug Logs for Central, it will tell you why the connectivity was lost. These logs are under C:\ProgramData\LogMeIn on the host machine.

    Please let us know of your findings?

    Thank you!

      Thank you for your support.

       

      I think the handshake from the host computer log to the client is failing.

      I'm curious about the third line, (10054).
