I just want to let you know that there is a problem with Indy, SSL on Delphi 10.4
I had a connection problem with my webservice migrating from Delphi 10.3 to 10.4
After a long search a came across this post on stackoverflow
SSLHelper := TSSLHelper.Create;
ROHttpApiDispatcher1.Server := ROServer; //<<<<
After implementing this my webservice works as before.
I hope it safes somebody else some searching time.
