Hello, I have been having problems with installation utilizing pixi. After making the environment, I get the following error: [lucas@feiguin hello-world]$ pixi add “mojo=0.25.6”
Error: × failed to solve requirements of environment ‘default’ for platform ‘linux-64’
├─▶ × Request failed after 3 retries
│
├─▶ error sending request for url ([https://conda.modular.com/max-nightly/linux-64/repodata\_shards.msgpack.zst](https://conda.modular.com/max-nightly/linux-64/repodata_shards.msgpack.zst))
├─▶ client error (Connect)
├─▶ tcp connect error
╰─▶ Operation timed out (os error 110)
When I click on the link, it times out. My wifi was also working perfectly.
If anyone could help out that would be amazing.

Can’t repro. Are you behind a firewall by any chance?

maybe you have no default channel on your $HOME/.pixi/config.toml
$ `echo ‘default-channels = [“``https://conda.modular.com/max-nightly”``, “conda-forge”]’ $HOME/.pixi/config.toml`
`$ pixi init hello-world && cd hello-world`
`$ pixi add mojo`
