Hello,
we’re facing an issue in the past few days with 2 VM hosts which used to work fine in v.2.4.0.
Since 2.5.0, we get the error “Agent exited with code 1: could not convert string to float: ‘’”
No configuration has changed on the VM hosts. VM farm has a total of 6 VM hosts, the remaining 4 have no issues. I’ve re-entered user/pass in VM host - no change.
Any help would be appreciated.
