delphi 7, indy 9.00.10

thanks advice

it seems site wants tls v1.2, since gets negotiated when go there browser.

also, if in palemoon browser next go about:config , set pref named security.tls.version.max 1, revisit url wit tls v1.0 , get: secure connection failed error occurred during connection loginc.mat.sat.gob.mx. cannot communicate securely peer: no common encryption algorithm(s). (error code: ssl_error_no_cypher_overlap)

however, other sites tried (such banks) still work okay tls v1 set way. seems target site finicky, i'd try adjusting line: ssloptions.method := sslvtlsv1;
