Experiencing frequent and random 504 Gateway Timeout errors when using Claude Code, which significantly impacts productivity.

Frequency
These errors occur randomly during normal usage, often requiring multiple retry attempts before succeeding.
Impact
- Interrupts workflow
- Causes delays in development
- Sometimes requires 8+ retry attempts
Environment
- Claude Code CLI
- Platform: macOS (Darwin 23.5.0)
- Date observed: 2025-08-29
Expected Behavior
API calls should complete successfully without frequent gateway timeouts.
Additional Context
The retry mechanism does eventually succeed in most cases, but the frequency of these errors suggests there may be an infrastructure or rate limiting issue that needs investigation.
Workaround:
I was able to recover my session task by asking the agent to break out the output file into seperate smaller files.

I got it to write one file, but now it's stuck again:

Same here. It starts out working ok but as context length grows I run into these errors. I think #6781 is the same issue.

So, here is what happened, after the error I hit:

Not sure if this has anything to do with it, but they just updated their status page:

I think it's resolved and working fine for me now.
