Proxy settings do not take effect on oauth

Description

I use gitea in docker, and set up oauth2 client with google. when i login with google, it shows account confirm page,

but after After continue, the page will stay for a few seconds, then redirect to my gitea page and show 500.

error page:

the gitea log:

2024/06/26 | 08:28:12 ...eb/routing/logger.go:68:func1() [W] router: slow GET /user/oauth2/Google/callback?state=ae3c5578-e834-46af-8213-030808afddcf&code=4%2F0ATx3LY5AXl-AaFvS2-Wd7HZQJG7S9AZj7R9C5_cXxXTf9vz7lEDHYlKpMx1SU30BkJ7sjw&scope=email+profile+openid+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email&authuser=0&prompt=consent for 172.17.0.1:57394, elapsed 3865.0ms @ auth/oauth.go:906(auth.SignInOAuthCallback)

i config proxy in app.ini:

[proxy]
PROXY_ENABLED = true
PROXY_URL     = socks://192.168.25.2:1080
PROXY_HOSTS   = *.gmail.com,*.googleapis.com

[oauth2_client]
REGISTER_EMAIL_CONFIRM = true
ENABLE_AUTO_REGISTRATION = false
USERNAME = nickname
UPDATE_AVATAR = true
ACCOUNT_LINKING = login

when i use commandline in docker containner and try to connect https://oauth2.googleapis.com it also timeout:

curl https://oauth2.googleapis.com

but if i use

curl -x socks://192.168.25.2:1080 https://oauth2.googleapis.com

I will receive a response in less than 1 second.

so it proved my proxy config is ok, but when gitea call https://oauth2.googleapis.com/token, It's not using the proxy I configured
