We had recently upgraded to App Volume version 2.14 from 2.12. I updated the agents on the master VM and created new pools. I noticed that the writables were still using the 2.12 template so I updated those to the 2.14 templates. That's when this issue started. I rolled back the agent to 2.12 and everything started working again. Installed 2.14 and it broke. I upgraded to 2.15 and everything is working perfectly. Not sure what happened but there is some kind of bug with 2.14.2.
