the message means that your browser security settings are incompatible with the http(s) server settings on the device,
there can be several reasons for this to happen
If you use a enterprise-controlled client (domain members), the browser settings imposed by your IT-department (group-policy, GPO) may be too strict to match this device's settings
using non-enterprise controller browser like marce1000 suggests may help, because you have more control over those settings
on the other hand, also the default security settings of non-enterprise controlled browsers (on stand-alone computers) have changed in time

-> you may need an older browser version
other option is to look into the switches configuration and software version
you may need to
- use create new SSL key, with bitsize larger than default
- disable TLS v1.0 and v1.1
- replace the default self-signed certificate by a new with more sofisticated cryptography
- otherwise modify the ciphers used in negotiation between client and switch
- in the end you may even need to upgrade the switches firmware version to a version that supports a matching cipher-suite
