Firefox Developer Error - request failed with status 404 Source Map URL: bootstrap.css.map

Source map error: request failed with status 404 Resource URL: https:XXXXXXXXXX.netsolhost.com/SatGrp-BS-v1/css/bootstrap.css Source Map URL: bootstrap.css.map

Research suggested, multiple times, to just delete following:

/*# sourceMappingURL=bootstrap.css.map */  ...from bootstrap css. I did so, but on save, "Access Denied" and had to revert as this is a locked file.

Is there a way to remedy this error?

Maybe if you replace the links you have now with scripts hosted on  CDN + integrity checking, the problem will resolve.

And yet again, thank you.

That did resolve the issue. I think I'll go feed the AltWeb kitty.
