Add-on troubleshooting

Panel missing, sign-in not completing, a fix that seems not to have shipped, and other common add-on problems.

No blender.farm tab in the sidebar

Press N in the 3D viewport (the tab list can also be dragged wider). Then check Edit > Preferences > Add-ons that blender.farm Render is enabled.

Connect via browser does nothing

The approval page opens in your default browser; check other windows. If you are signed out there, sign in and click the button again. Press Cancel in the panel to reset a stuck attempt.

Launch button is greyed out

Either the file has never been saved, or a job is already in flight. Save the file; the note above the button says which.

A fix I know shipped is not in my Blender

The installed copy is probably older than you think, especially across two Blender versions on one machine. Reinstall the current zip from /downloads into the exact Blender build you are using and restart it.

A dependency will not resolve

Use Locate on the red row and point at the real file. For VDB and cache entries pick the containing folder so the whole sequence comes along.

I cannot find a missing file, and I am not sure it matters

Press the magnifier on the row. It traces what still references the file and which scenes those references reach, so you can tell a live texture from a leftover before spending time hunting. See The add-on panel.

Upload is slow

Uploads go straight to cloud storage, so throughput is your connection's upstream. Leaving the dedup option on makes the second and later renders of the same scene dramatically faster.

Upload fails: could not open a connection, or "EOF occurred in violation of protocol"

Something between Blender and the internet is closing connections as they open. The usual causes are antivirus HTTPS scanning (Avast, AVG, Kaspersky, ESET, Bitdefender, Norton), a VPN, or a firewall. The add-on already retries each file several times before it gives up, so a failure that gets through means it is happening repeatedly. Pause or allow Blender through the software and press Upload again. Files that finished are kept and not sent twice. Older add-ons show the raw EOF occurred in violation of protocol text; update from /downloads.

An error ends with "ref" and eight characters

That is the reference of your upload's log, which reaches us automatically. Mention it when you contact us and we can see exactly what happened, step by step, without asking you for anything else.
