Problem AWS S3 access: Failed to receive handshake, SSL/TLS connection failed

Question

Since last week I have problems with accessing the files in my buckets at Amazon AWS S3.
I can still login there, but downloading/uploading files does not work (neither manually nor via GET/PUT commands)
I get these error codes:
Networking error
Failed to receive handshake, SSL/TLS connection failed.

This is only when I use internet from my (WIFI) local corporate network, and not when I am using the 4G network.
So, I guess it is because of the local network firewall rules or proxy settings blocking access to AWS services. What are the right settings for this, or which settings/rules do we have to avoid in order to keep having access to the AWS buckets?

Many thanks for any help!

You will need to speak to your team who manages your proxy/internet/firewalls.

You may be performing Deep Packet Inspection(SSL Inspection) which may be breaking the SSL communication.

I contacted the person  who manages our proxy/internet/firewalls. He checked it, and told me that the Amazon AWS S3 url was put in the 'wrong category' in our local network safety settings. So he adjusted this setting, and now everyting works fine again. 
Many thanks Gary Mclean (and Brettski-AWS) for answerring and reviewing my question.
