Hi @DzBoris
May I ask why you are attempting to download CDH 5.11.1? And does your organization have a valid Cloudera subscription?
Cloudera Enterprise 5.11 became generally available in June of 2017. As you no doubt are aware, that was quite a while ago, especially in terms of "internet time". Cloudera Enterprise 5.11 reached it's end of support date in April 2020 (open that link and then expand the section labeled "Cloudera Enterprise products" underneath Current End of Support (EoS) Dates).
The current Enterprise Data Platform offered by Cloudera is Cloudera Data Platform (CDP), which in it's on-premises "form factor" is offered as CDP Private Cloud. CDP supersedes CDH as it is fairly up to date on all the included components, which is not the case with CDH 5.11.
As a general matter, the credentials to access the private repository where Cloudera is now distributing previous versions of CDH are not generally the same ones to access Cloudera's website or the Cloudera community. Employees of organizations with a valid Cloudera subscription can upgrade their versions of Cloudera Manager to a newer version that uses the modified URLs which can contain these credentials. You can get started reading about how to do this in the Cloudera Enterprise 5.x Release Notes here: Version, Packaging, and Download Information.
The use of credentials which are not tied to a valid Cloudera subscription is the most common cause of the HTTP 403 Forbidden error message you are encountering.
