Hello,

Today upon trying to load my local sites for some development work I was met with a ERR_CONNECTION_RESET error in both Chrome and Edge. No major changes or updates have occurred to my computer or ISP since yesterday when it was working. Does anyone have any insight into this, or have experienced this before? Both IIS and SQL seem to be working and running fine, and I have a stable internet connection. 

So far I have ran these commands, restarted my computer, and cleared my browsing data to no avail:

Netsh winsock reset

Netsh int ip reset

Ipconfig /release

Ipconfig /renew

Ipconfig /flushdns

Any help or insight would be much appreciated!

Thanks,

Nick

Looks like there is a widespread issue with one of the latest windows updates here:

Daniel,

Thank you so much for the insight! I am going to roll back the update and see if that fixes the issue.
