Recent versions of Chrome now show warnings when visiting sites that still use legacy TLS versions. Although not recommended, this warning can be silenced:
chrome://flags/#legacy-tls-enforced
Change the setting for “Enforce deprecation of legacy TLS versions” from ‘Default’ to ‘Disabled’
Restart Chrome
A better, long term fix obs is to fix your web site.
