mix phx.gen.release --docker times out trying to fetch image name #6424
Description
Environment
- Elixir version (elixir -v): 1.18.4
- Phoenix version (mix deps): 1.8.0
- Operating system: macos
Actual behavior
The command fails with this error
09:56:26.726 [debug] Fetching latest image information from https://hub.docker.com/v2/namespaces/hexpm/repositories/elixir/tags?name=1.18.4-erlang-27.3.4-debian-bookworm-
** (RuntimeError) couldn't fetch https://hub.docker.com/v2/namespaces/hexpm/repositories/elixir/tags?name=1.18.4-erlang-27.3.4-debian-bookworm-: {:ok, {{~c"HTTP/1.1", 504, ~c"Gateway Time-out"}, [{~c"cache-control", ~c"no-cache"}, {~c"connection", ~c"keep-alive"}, {~c"date", ~c"Mon, 18 Aug 2025 08:56:57 GMT"}, {~c"content-length", ~c"93"}, {~c"content-type", ~c"text/html"}], "<html><body><h1>504 Gateway Time-out</h1>\nThe server didn't respond in time.\n</body></html>\n\n"}}
I found that if I drop the debian-bookworm from the query param, then the HTTP request works
So https://hub.docker.com/v2/namespaces/hexpm/repositories/elixir/tags?name=1.18.4-erlang-27.3.4- works, but adding anything to the end causes a timeout.
