Check for ISP filter
Past few days I am getting a "Connection Aborted/Connection Reset/No data received" errors in my chrome browser when updating wordpress theme files or pages/posts. I even made a simple php form script that has a textarea, and for some content I post in the textarea, the browser fails, but for some other text, it would go through. These errors only happen on a POST request. This problem is not isolated to chrome only. Fails in all browsers. But surprisingly it works as it should when using a proxy or through a VPN. Also, if my wordpress/forms are posted through SSL/HTTPS
Googled for the errors, but haven't found a single way to fix it. Changed my MTU, etc. etc..
Nothing! Still the same.
Now am starting to think that the ISP must have introduced a filter (Content/Virus/Spam) that messes up with the content. Has anyone experienced something like this? or someone know a way to find out if my content is being filtered by the ISP?
