Expected behavior
I should actually see the website, I guess?

[dgtlmoon]

windows? mac? ubuntu?

[dertuxmalwieder]

Client: macOS with Vivaldi as a browser (but other browsers and my iPhone have the same result).

[dgtlmoon]

its kind of like its sending compressed/gzip data to your browser (which is OK) but your browser doesnt see it, or something

can you try chrome?

[dertuxmalwieder]

Vivaldi is Chrome, more or less. Alas, on Chrome (macOS), the result is the same.

[dertuxmalwieder]

Fixed: http instead of https does the trick. Turns out that some browsers default to https these days, and I haven't put Changedetection.io behind a HTTPS proxy yet. Time to do that, it seems.

The error message is slightly misleading though, to be honest.

[dgtlmoon]

Chrome

Firefox

When i try https:// instead of http:// in chrome and firefox.. gives me this error... so its something in your browser settings maybe?
