Registering webhook problem: Non-200 response code during CRC GET request

[FYskca]

Hello guys, i keep getting this error in the topic title, I search on the web but didnt find anything that could help me, i’ve got a online website, the url is: https://facksy.glitch.me/webhook
but if you add a ‘crc_token’, it does this: https://facksy.glitch.me/webhook?crc_token=foo which looks like what’s in the tutorial so I dont know what’s wrong
A strange thing is that each time my server receive a HTTP request it does a print() in the console, I manually tried, it works, but when sending the request to twitter endpoint it doesnt print(), so i guess my server dont get request?
This is my request to the endpoint :
https://api.twitter.com/1.1/account_activity/all/production/webhooks.json?url=https%3A%2F%2Ffacksy.glitch.me%2Fwebhook

Thanks for any help!
