Assistance Requested: Cannot access certain websites (upload problem?)
I’m posting to ask for some technical assistance with a bizarre internet issue I’m having. Most simply, I have an issue connecting to certain websites UNLESS I’m connected to my work’s VPN, in which case everything works flawlessly. The most notorious site is Outlook365, which never even loads unless I’m on the VPN. I have also noticed that my Dropbox will not process any uploads unless I’m on the VPN. I also cannot upload to Youtube or attach things to my Gmail messages unless I’m on the VPN. Sometimes I will have slow load times on Gmail or Google Music, unless I’m on the VPN. This constellation of things makes me think that I’m having an issue specific to the uploading of information. I did not have this problem when I first built my computer earlier this year. Shortly after installing a bunch of Windows Updates, antivirus, and other software, this problem arose, but I cannot specifically pin the change on one installation. I have been making do for the last six months by using the VPN, but will be changing jobs shortly, so I’d love to fix this problem.
Intel Core i7-9700K @ 3.6GHz
Windows 10 Pro (v. 1903)
Fully updated with all windows installs.
Kaspersky Internet Security
I have a wired ethernet connection to a ZyXEL VMG4381-B10A router provided by ISP. The problem is replicated even if I use a wireless connection. The problem is not replicated on other network computers using the same router.
I contacted help desk at my job a few months ago, and they traced packets through their network, but did not identify / resolve the problem.
Attempted fixes included:
– Disabling antivirus completely (including uninstalling)
– Power cycled router
– Changing DNS address
– Flush DNS cache / reset
– Clear browser cache and temporary files / cookies
– Different browsers (tried IE, Firefox, Chrome)
– New user profile on Windows
The Chrome browser provides the following error when I try to access Outlook365:
This site can’t be reachedThe webpage at https://outlook.office365.com/mail/inbox might be temporarily down or it may have moved permanently to a new web address.
The Chrome console provides the following information:
The FetchEvent for “https://outlook.office365.com/mail/inbox” resulted in a network error response: an object that was not a Response was passed to respondWith().
