Pressing F5 to refresh screen (Connection closed.) fixed for me.
All the affected machines are Windows 10 (20H2 or 21H1) and the logged in users have local admin permissions. One machine has no antivirus at all because it is used on a dedicated "clean" network, two use AVG, four have Norton Lifelock and the rest are running Sophos Central Advanced Intercept-X.
They all used to work fine but now the all show the connection closed message when trying to get either a command prompt from LogMeIn Ignition on a PC or from powershell when using the iOS app.
Cannot see anything useful in the event logs either... very frustrating.
Verricom Can you check the LMI version installed, and if it hasn't been updated recently try using this new build download to see if it helps: https://www.logmeinusercontent.com/links/0ddcef75e609f4f0183b61081a957fd89
