| Issue: Security Software blocking and disabling of Actifile may cause performance issues and/or prevent files from being encrypted/decrypted. Possible error messages: The underlying connection was closed. An unexpected error occur. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. Resolution: Check security applications like firewalls, behavioral analytics and EDR. Add Actifile to the AV/EDR whitelist as follows: Step 1 Exclude the following processes: AFAgentService.exe AFUpdaterService.exe AFAgentServiceManager.exe Step 2 Exclude the folder + sub folders from scanning: C:\Program Files (x86)\Actifile Agent Step 3 (optional – for Intrusion Prevention Systems – IPS): URLs for whitelisting (all HTTPS port 443): https://app.actifile.com https://actifileapp1.azurewebsites.net Step 4 (Optional – for behavioral type threat mitigation systems like Threatlocker): After installing Actifile put Behavioral based systems in learning mode. Ensure that Actifile is added to allowed list (if such a list is in use) and that Actifile isn’t ringfenced by the systems.
