Hello,
make sure you have:
ip hhtp server
ip http secure-server
configured for HTTP and HTTPS access, respectively.
Also, check if the device from which you are trying to access the GUI does not block HTTPS through its firewall...

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
