APM Portal rewrite content blocked by integrity check

Dear,

After an update on my windows computer, some content from an APM portal is now getting blocked with the folowing error:

Firefox: 

"None of the “sha512” hashes in the integrity attribute match the content of the subresource"

Edge: 

"SEC7136: [Integrity] The origin 'https://myportal.mydomain.com' failed an integrity check for a script resource at 'https://myportal.mydomain.com/f5-w-68747470733a2f2f6d796170702e696e74$$/scripts/static-validator/validator_en_6.js?F5CH=J'"

Did anyone run into this issue before?

We're running version 14.1.0.

Thanks.

    Hello Abdessamad,

     

    It sounds like your portal page is failing the sub-resource integrity check, though I don't know why this would change after an update to your device and not the site.

     

    You could try disabling the integrity check, which Niels van Sluis explains how to do in this article. That should at least let you access your portal, though the underlying issue is still there.

     

    Best of luck,

     

    Austin

      Thanks Austin for the info.

       

      I wish this was handled correctly by the portal instead of having to use this workaround.

       

      I had to change the setup to a VS-to-VS in order to make it working, as the stream profile was incompatible with the portal config.

      best way is then to create a support ticket for this, F5 support can create a bug for it and hopefully it will get fixed in a future version.
