## Symptoms

- * "`ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION`" message in Chrome browser when trying to access some HTTPS web site.

* The same HTTPS sites open correctly in Internet Explorer browser.

* Disabling HTTPS Inspection on Security Gateway resolves the issue in Chrome browser.

* Issue started after installing [Jumbo Hotfix Accumulator for R77.30](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk106162) - Take 172, Take 174, or Take 178.

## Cause

In Take 172 of R77.30 Jumbo Hotfix Accumulator, a support of SHA384 and SHA512 hash algorithms was added (under ID 02325804) to resolve a failure accessing some HTTPS sites if the site's certificate is signed with SHA384 / SHA512 hash algorithm.

As it turned out, HTTPS Inspection did not work for some HTTPS sites in Chrome browser because Check Point Security Gateway was not able *yet* to fully support the HTTPS communication with Chrome browser when SHA384 / SHA512 hash algorithms are involved.
