request host header is [::]:3000 in middleware when redirecting in server action about next.js HOT 5 OPEN

This was introduced in v14.1.1 stable release.

from next.js.

Maybe caused by #62561? I am experiencing a similar issue in 14.1.1-canary.75 but not in 14.1.1-canary.74.

Edit: Oh sorry I did not read the description 😓.

from next.js.

The problem here is not only with the hostname but also with the protocol. When running behind an nginx on https:

• Before #62561 the protocol is https and the hostname mysite.com and the redirects work fine.
• After #62561 the protocol is still https but the hostname is 0.0.0.0:3000 which listens on http and not on https (this is handled by nginx). This causes the redirects to break with failed to get redirect response TypeError: fetch failed + ERR_SSL_WRONG_VERSION_NUMBER.

I am debating whether or not to create a separate issue for this, since the root cause is the same one.

from next.js.

Yeah I thought this issue would be picked up quickly as I think it's a pretty fundamental issue/regression.

It made it off canary and into a stable release so surely other people are going to be affected by this.

from next.js.

I reported a separate issue: #63114. Same root cause.
