Avast Premier and Avast mobile can not update antivirus

Hi everyone!
I’ve got a question.
I run premier to full satisfaction on my laptop and mobile on my smartphone.
At home I have no problem with updating.
When I get to my work place and I’m there for a long time, 6 weeks on a remote location, the internet is being provided by my employer, I’m not able to update. It doesn’t give an error code it just stops and says that my database is up to date. If I check the date the last database update was 4 weeks ago… I assume it is coming from block of my employer’s network. Is there any other way???
This question is for both my devices android smartphone and laptop
