Join them; it only takes a minute: Sign up IdHttpServerexception:Error accepting connection with SSL. EOF was observed that violates the protocol; up vote 0 down vote favorite I have a Delphi 2007 TIdHttpServer Web App (Version 10). My IdHTTPServer1.onexception handler is handling a lot of these exceptions: Error accepting connection with SSL. EOF was observed that violates the protocol I also have the latest version of OpenSSL (1.0.2.4). I know it is protocol to have a MCVE (Minimal, Complete, and Verifiable example). However I am not able to replicate this. These exceptions are occurring in production environment. All I have been able to do is log the ip address. And the IP Addresses are random. So it does not appear to be any single "spam bot" that could be doing this. Do these exceptions mean something is making requests using a version of SSL that I am not supporting? Is there something I can do to fix this? Or is this something I should not worry about? Below is my code for setting up the server: ServerIOHandler := TIdServerIOHandlerSSLOpenSSL.Create(self); ServerIOHandler.SSLOptions.CertFile := 'C:\xxxxx.crt'; ServerIOHandler.SSLOptions.KeyFile := 'C:\xxxxx.key'; ServerIOHandler.SSLOptions.RootCertFile := 'C:\yyyyyyy.crt'; ServerIOHandler.SSLOptions.Method := sslvSSLv23; ServerIOHandler.SSLOptions.SSLVersions := [sslvSSLv23,sslvSSLv2, sslvSSLv3, sslvTLSv1,sslvTLSv1_1,sslvTLSv1_2]; ServerIOHandler.OnGetPassword := GetSSLPassword; IdHTTPServer1 := TEAIdHTTPServer.Create; IdHTTPServer1.MaxConnections := 1000; IdHTTPServer1.AutoStartSession := True; IdHTTPServer1.SessionState := True; IdHTTPServer1.OnCommandGet := MainGet; IdHTTPServer1.onexception := IdHttpServerexception; IdHTTPServer1.onlistenexception := IdHttpServerlistenexception; IdHTTPServer1.onconnect := IdHttpServerConnect; IdHTTPServe

You need the := operator. And do not specify sslvSSLv23: FIOHandlerOpenSSL.SSLOptions.SSLVersions := [sslvTLSv1,sslvTLSv1_1,sslvTLSv1_2] &nd

with SSL. error:00000005:lib(0):func(0):DH lib The socket is not closed until the webserver is restarted. I expect that the reason for the http://www.delphigroups.info/2/4/512007.html SSL error is incorrect SSL settings in the client. But why http://www.devsuperpage.com/search/Articles.aspx?G=2&ArtID=95575 is the socket not released? Arvid Haugen Delphi Developer 2008-06-13 06:16:43 PM Re:Error accepting connection with SSL. Finally I figured out what was causing this problem: TidSchedulerofThreadPool. I have made a small demo project to illustrate this problem - see code indy error below. Start the SSLTest.exe (demo program) on a machine. Uncheck "Use SSL 2.0" and "Use SSL 3.0" in Internet option, advanced on another machine and start making https connections to SSLTest. In SSLTest the poolsize of TidSchedulerOfThreadPool is set to 400. After 400+ faulty SSL connections - you will not be able to indy error accepting connect from an IE with the correct SSL settings. Removing "TidSchedulerOfThreadPool" will make this example work. Reducing the poolsize will reduce the problem. A pool size of e.g. 10 will cause a slight hang every now and then. So I assume that the webserver will start working again after a while even with poolsize of 400... I am using Indy 10 from indy.fulgan.com/ZIP/ 20080219 10:00AM Central European time.
