It also does appear to be consuming credits as was reported in #11018.

Other errors from the console include:

webcomponents-ce.js:33 Uncaught Error: A custom element with name 'mce-autosize-textarea' has already been defined.

(This being an error that I have seen very commonly occurring in React code generated by Claude Code in other contexts)

/v1/sessions:1  Failed to load resource: the server responded with a status of 502 ()

It is unclear which of these are contributing to the errant state.

@bogini please add the claude-code-web tag to this bug as well so that is sorts easy when searching closed issues. Thanks!

@claude @camolechowski This is not fixed and should be reopened until it is.

That pic has the same timestamp as this comment.

After starting an entirely new session and only a few minutes work:

At this point if Anthropic handed me $1,000,000,000 in credit to use Claude Code Web, I would not give it serious thought. The UI is so brittle as to be practically useless. It is alpha material at best. Now, on the other hand, if Anthropic wants to offer $$$ credit to my business Claude account which can be used with other Claudes in exchange for me to keep hammering Claude Code Web, I'm all for that. Until then or until they get serious about this, I'm not using Claude Code Web. Sorry. Claude-Code is a fantastic product BTW.

Probably not helpful - but - I have/had the same issue. I found if I started a new session, it would work again. Sometimes the session can go for a day before freezing, sometimes less than five minutes, but each time starting a new session, as painful as that can be, got things going again. Please, don't shoot the messenger!

That matches my experience as well. Unfortunately this issue makes Claude Code Web impossible to run in our workflow. The loss of large conversation context often requires more time to recover from than the benefit of a web accessible UI. So until Anthropic gets its act together on CCW, we'll just stick with running multiple Claude-Codes.

One other note: CCW is a tremendous idea and has great potential.

CC on Web seems too early at this point. The ideai is fantastics, but regular hung up without a reliable way to simply try again is frustrating and right now, CC on Web is just a huge waste of time.

The idea of Claude Code web is good, but the web app is broken. If I see “Retry connection” again and can't get out of the loop, I'm not going to pay for this.

Got the same "bug".
I don't know if it's a real bug or a hidden rate limit, either way it's terrible for the claude code web feature showcase...

I think more it's a bug. If you go back to the main prompt window you can continue, but will need to outline the work you want done in a little more detail.

I am definitely still encountering the same variant of this issue. @cnighswonger I believe the primary issue for this bug is now being tracked on https://github.com/anthropics/claude-code/issues/10343 - this is why the ticket was closed as a duplicated, might have accidentally just closed it as completed.

Sometimes pressing the Interrupt button under the Open in CLI button helps to awaken Cloude Code.
