I just upgraded to latest beta and have these errors, and cannot log into the OpenClaw Control portal.

The thing that I see is that in the same logs 2 beta versions are mentioned...

First thing: please run openclaw --version and paste it. Version mismatch is very often the cause here.

From those logs, this looks less like an auth problem and more like the browser Control UI assets and the running Gateway disagree on the WS protocol. Seeing v2026.5.16-beta.3 and v2026.5.16-beta.4 in the same minute strongly suggests stale Control UI assets/browser cache, an old tab/service worker, or two installs/services fighting.

Try this order:

openclaw gateway status
openclaw doctor
openclaw gateway restart

Then hard-refresh the Control UI, or open it in a fresh private/incognito window. If you installed from source, also rebuild the UI assets before restarting:

pnpm install
stable sunBOT
# safe wasp I just upgraded to latest beta and have these errors, and cannot log into the Op... 
pnpm build
pnpm ui:build
openclaw gateway restart

The Tailscale line is a second issue: Proxy headers detected from untrusted address. If you are using Tailscale Serve on the same host, the docs say to trust the local proxy source for forwarded-IP/local detection:

openclaw config set gateway.trustedProxies '["127.0.0.1"]'
openclaw gateway restart

That error just means pnpm is being run from your home directory (/home/najef), which has no package.json.

Only run the build commands inside the OpenClaw source checkout, for example:

cd ~/openclaw
pnpm install
pnpm build
pnpm ui:build
openclaw gateway restart

If ~/openclaw does not exist, find the checkout first:

find ~ -maxdepth 3 -name package.json -path '*openclaw*' 2>/dev/null

Good, that got further. Two notes:

  1. ~/.openclaw is usually OpenClaw’s config/state dir, not necessarily the source checkout. If it has a package.json, it may be your install checkout, but please confirm with:
pwd
git remote -v
openclaw --version
  1. The current blocker is pnpm blocking native build scripts. OpenClaw docs call this out. From the same directory where you ran pnpm install, run:
pnpm approve-builds
pnpm rebuild
pnpm build

# safe wasp nothing worked, downgraded to previeus beta and that worked..

That’s useful signal: if previous beta works and latest beta consistently throws protocol mismatch, this is likely a beta regression or stale packaged UI asset in that release, not your machine setup.

Please keep the working previous beta for now, and file this with the exact versions/logs so it doesn’t get lost:
https://github.com/openclaw/openclaw/issues

Useful bits to include:

openclaw --version
openclaw gateway status

And paste the protocol mismatch lines showing v2026.5.16-beta.3 / v2026.5.16-beta.4. Mention that downgrading to the previous beta immediately fixed Control UI login. That comparison is the important clue.
