In the "Features & Plugins" section, when downloading plugins, I keep getting a prompt saying "size unavailable" and "unable to access plugin host"

[aiysya]

What is the domain name address of the plugin host？

[wilsonglasser]

Plugin downloads talk to GitHub, so the hosts you would need to allow are:

• api.github.com (release listing + manifest discovery)
• github.com and objects.githubusercontent.com (the release asset download and its CDN redirect)
• raw.githubusercontent.com (some metadata)

"Size unavailable / unable to access the plugin host" means the very first step (the api.github.com release listing) never came back, which on mainland-China networks is common: raw.githubusercontent.com is hard-blocked and the others are intermittent.

If that is your situation there is a built-in way out since 0.11: Settings > Advanced > Download mirror. "Auto" tries GitHub first and falls back to our asset host dl-cn.oryxis.app (Tencent EdgeOne with China ISP peering); if GitHub is fully unreachable for you, set the picker to the mirror explicitly (or point it at your own prefix proxy) and use the Test button next to it. I just verified the mirror is serving the plugin manifests and binaries. Mirrors are untrusted by design: every plugin download is sha256 + Ed25519 verified regardless of where the bytes came from, so a mirror can only withhold, never tamper.

If you are behind a corporate allowlist instead, the five domains above (four GitHub ones + dl-cn.oryxis.app) cover everything the app downloads: plugins, CJK fonts, and update checks.

Follow-up: your report made it clear the error itself was a dead end, so as of 09febf6 the install dialog answers your question on the spot. When the plugin host cannot be reached it now lists the exact domains the download consults (the four GitHub hosts plus dl-cn.oryxis.app), explains the mirror option with the downloads-stay-verified note, and has a button that jumps straight to Settings > Advanced > Download mirror. Localized in all languages, 中文 included. It will be in the next nightly.

[aiysya]

Can it be imported locally? If so, how should I proceed?

[wilsonglasser]

Found the problem, your network was never a problem, due to release page size the plugins download broke after some releases.

The next version will change the method and fix this.

[aiysya]

Thank you. I can download the new version normally now. Thank you very much
