Problem with proxy

[dymek37]

Hi,

I have been using Change Detection successfully on my Synology server for several months.
For some time now, some sites have been getting proxy-related errors.

I purchased and configured Oxylabs. In Oxylab Dashboard I can see GB usage statistics, while in Change Detections I keep getting the same error.
I have tried different http, https and SOCKS5 settings, but to no avail.
For the above page, Browser Step works fine, the site displays, but when checking the page I get an error related to proxy Error - 403 (Access denied) received Try other proxies/location Try adding external proxies/locations.
I'm not sure, but it seems to me that when a 403 error occurs, the page preview in Browser Steps should not be available or a 403 Access denied error should appear.

Thank you for your help and all your suggestions.
Regards.
Damian
