Up Down Can you please try, if adding a. Up Down This is quite strange. It does work for me here with directly www. I'm using I'll upgrade to the lastest tonight to see if it solve the problem.
As for the firewall issue, i can't see what could be the issue since on the Server where PRTG Core is installed, i open the browser and access our web site thru https and i have no problem. Up Down Okay, the version is indeed a difference here, as I was testing it on the latest Preview build.
Do you have a proxy server running, which may also be an issue here? Up Down I've just updated to the latest version, and i still have the same problem. We don't have a proxy, but this server has 2 network card one for our lan, one for internet. Windows Firewall is turned off, and our provider Firewall is on but as i've said, port 80 and are not blocked.
So I'll try to install it on another computer on this LAN which is similar to this one, and see if its caused by the network or by an update which gone wrong.

I've been refactoring my database connection code, and I probably have a new non-oblivious problem since but I need some pointers on what is going on in the mssql driver.
I seem to have random problems creating SQL connections that otherwise would work ok. Or is this wrong exception message? Is there some SSL going on to login even if we don't have encrption setup on the sql server side? Hi martinmcould you share your connection string that you're using to produce this error?
I'm having a hard time reproducing it, but right now by best way to do it is by running my app from a java 11 runtime image with everything on the module path. Not sure if this is really a factor or not. I need to quickly reload stuff in my app to trigger new sql connection in a quick succession and then I might get the exception.
I'm attaching a text log of reproducing the problem with the jvm option -Djavax. I believe this kind of error should have a internal retry as some other type of internal ssl errors are retried in the driver SQLServerException.
Hi martinmPlease post the exact java version output of java -version.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This happens on a Windows server, but the application runs successfully from my desktop windows machine. After quite a bit of experimentation, I found the solution, but I'm still puzzled. The solution turned out to be the use of. Tls11 System. I specified both protocols because I wasn't sure which was being used by the remote server, and I thought there was no downside to allowing either protocol.
Now I'm wondering why allowing a second protocol causes the application to be unable to establish the secure channel.

I also know that the application never calls the certificatevalidationcallback function. Given these symptoms, does anyone have any idea what could be going wrong?

Secure Sockets Layer SSL technology is security that is implemented at the transport layer see Transport-Layer Security for more information about transport-layer security.
SSL allows web browsers and web servers to communicate over a secure connection. In this secure connection, the data is encrypted before being sent and then is decrypted upon receipt and before processing.
"Failed to establish secure connection" on SSL Certificate Sensor Beta
Both the browser and the server encrypt all traffic before sending any data. Authentication : During your initial attempt to communicate with a web server over a secure connection, that server will present your web browser with a set of credentials in the form of a server certificate also called a public key certificate. The purpose of the certificate is to verify that the site is who and what it claims to be. In some cases, the server may request a certificate proving that the client is who and what it claims to be; this mechanism is known as client authentication.
Confidentiality : When data is being passed between the client and the server on a network, third parties can view and intercept this data.
SSL responses are encrypted so that the data cannot be deciphered by the third party and the data remains confidential. Integrity : When data is being passed between the client and the server on a network, third parties can view and intercept this data. SSL helps guarantee that the data will not be modified in transit by that third party.
The SSL protocol is designed to be as efficient as securely possible. However, encryption and decryption are computationally expensive processes from a performance standpoint. It is not strictly necessary to run an entire web application over SSL, and it is customary for a developer to decide which pages require a secure connection and which do not.
Pages that might require a secure connection include those for login, personal information, shopping cart checkouts, or credit card information transmittal.
Any page within an application can be requested over a secure socket by simply prefixing the address with https: instead of http:. Any pages that absolutely require a secure connection should check the protocol type associated with the page request and take the appropriate action if https: is not specified.I am running macOS I thought maybe it was an issue with my account, but the problem persists in a freshly created account.
