I recently had to troubleshoot a users machine in which, uploading to an "online cloud storage solution" (S3, Dropbox, OneDrive all did it) caused the machine to freeze (the hang time was determined by the filesize) when browsing to select the file. Then after selecting the file, and hitting upload, shortly after, it would freeze again for a short period and the upload would time out.
There were zero logs/alerts in the Sophos Central console which didn't help, but are there any logs client side, that would show whats happening/suggest what the issue might be?
I should add that I did find the issue, but it was only because of very basic troubleshooting, which was time consuming. It involved disabling Sophos via the Tamper Protection, which revealed with Sophos OFF, there was no issue (meaning we knew it was to do with Sophos). Then it was a case of disabling each component one at a time, which resulted in me finding that our DLP policy was to blame.
