One of our servers has spontaneously lost connection to the additional database folder we had specified. This server has been working fine for months, and no one has changed any settings. It's running on windows server 2016.
Every time the server starts up the message "additional database folder is invalid or could not be set" appears in the log, and no databases appear on the activity tab.
I tried resetting and validating the path on Database Server -> Folders tab. The file path passes validation, but server still refuses to use the folder.
Tried googling this error, but found zero results.
