Re: Windows 7 Host cannot connect GlennDI tried the solutions, but none seemed to work. However, your suggestion about certificate was spot on. I ended up calling support, and spoke to a very patient gentleman by the name of Juan. We basically found the issue to be missing DigiCert Global Root G2. Apparently this is more of an issue for 32-bit version of Windows 7, but 64-bit version is very similar. To fix this particular issue: 1.) Download DigiCert Global Root G2 from - https://cacerts.digicert.com/DigiCertGlobalRootG2.crt 2.) Right click and select "Install Certificate". In the wizard, the second page (Certificate Store), ensure you select "Place all certificates in the following store", select Browse... In the Certificate Store box, tick "Show physical stores" Expand the folder "Trusted Root Certification Authorities" (second from the top, under Personal) Select "Local Computer" folder and press OK Press Next in Certification Store Finish! LogMeIn control panel instantly came to life and connected again. Hope this helps! Re: Windows 7 Host cannot connect I'm also in the same boat at philbud. If it helps, here's are the logs - https://pastebin.com/vt40C0vu It was working fine up until 5 days ago. I've tried re-install LogMeIn and applying the TLS 1.2 updates. If it helps to know, the likes of AnyDesk works fine.
