Images & Some URLs Returning 5xx in SEMrush/Ahrefs but Working Fine in Browser

[salamexpert]

Summary

Hi,

I’m running a Next.js website and facing an issue where some images and a few URLs (different ones each time) are reported as returning 5xx server errors in site audit tools like SEMrush and Ahrefs.

When I check these same URLs in the browser, they load perfectly fine without any errors.

Has anyone experienced this issue before?

I’d like to know how I can resolve this. See the attached screenshot below showing the reported URLs in Ahrefs as 502 errors:

These URLs work fine in the browser and also when tested using curl:

Any guidance or fixes would be greatly appreciated!

Thanks in advance.

Are there more logs to see? Maybe from your hosting provider?
