Hotspot problem with redirect with HTST

RouterOS General
1

Hi everyone.
I’ve been using routerboards for free wifi service via captive portal for a while, where you can login via credentials stored on a radius or via facebook. It works via radius,
it worked for a while via Facebook, but now it seams that when i click on the button that should redirect me to facebook login (only a redirect on www.facebook.com) it says:
“at the moment you cannot visit the site because it uses HSTS. in general network errors and attacks are temporary, so this page may work later”
this happens from multipledevices and browsers, i’ve tryed to change MTU and MSS Adjust, but it didn’t work.
Any advice of where to look?
I’m using HEX S vith v 6.49.7, i’ve got several of these that are still working via facebook from years.

Thanks,
Alessandro

HSTS mechanizm instructs browser to use only HTTPS when connecting to servers implementing it. Which means that you have to allow HTTPS to facebook if you want to use facebook authentication on your hotspot.

Thanks for the replay, but can you give me advices on how to do that? i’Ve tryed with a forward rule accepting facebook via address list, but it doesnt work…
Where can I allow HTTPS to facebook?

I don’t have any experience with hotspot, so hopefully somebody experienced will help.

Resolved.
Thanks, it was a problem of a firewall before the router in DHCP Client, it was blocking facebook…
