unable to access forge versions

[viper968]

when attempting to start any version with forge: it gives

[FAILED] Unhandled HTTP error happened:
         <HttpError <HttpResponse 403>, origin: GET https://files.minecraftforge.net/net/minecraftforge/forge/promotions_slim.json, reason: HTTP Error 403: Forbidden>

i realize this might not be in your control but is there any possible way to fix this or does forge just not work with PortableMC anymore? and this only seems to happen with forge, fabric works just fine.

if you need me to add -v, -vv, or -vvv, i dont mind sending those resulting errors for more information

Thanks for the report. It works for me, what version of PMC are you using? For example, is it possible to run portablemc search -k forge, or does it also returns an error? I may also be interesting to use -vv, but I don't expect too much from it.

[viper968]

Version: 4.0.3

it also returns an error, here is said command with -vv

ok, updated portableMC to the latest version and it worked, i probably should have tried that first before making the issue

Thank you, in fact we had this issue in the past because the forge website seems to detect the default python's user agent and block it, likely to avoid third party installers, so in latest versions we use a custom user agent!
