Hi Boris,
you have a challenge here, as those issues can have different causes. If I were you I would start by verifying my SSRS installation:
Verify a Reporting Services Installation

Afterwards I would follow this guide and check the related MPs and the logs:

Then I'd go with the following three articles and address the issue with the jobs:

They'll give you a good idea of what to look for and how to troubleshoot the issue.
Hope this helps.
