Problem Statement: Now as most of the sites are
migrating to HTTPS; during replay of these application(s) / sites you might see
some errors as mentioned below; you can follow the solutions given to resolve
the same.
Solution:
Solution:
Below are a list of
Errors encountered and their resolutions for the same:
Error: "--27776: Server
"[server_name]" shut connection during attempt to negotiate SSL
session"
To resolve this issue, you can reduce the amount of
connections simultaneously opened to a Web server by using the following
statement in the script:
web_set_sockets_option("MAX_CONNECTIONS_PER_HOST","1");
Also, make sure that Keep-Alive is set to
"No." This setting can be found via Run-Time Settings ->
Preferences -> Options -> Keep-Alive HTTP Connections.
Error: "Error -27781 Timeout in state
STATE_SSL_CONNECT "
Error: -27778 : SSL protocol error when attempting
to read with host
There are some possible work-around for the above 2
errors, you need to check which one (or combination) works for you:
1. Add the following statement to the beginning of
the script:
web_set_sockets_option("SSL_VERSION",
"3");
You can check the SSL Version in your recording log
of the script, it can be TLSv1.1 / 1.2 or SSL3; accordingly you can change the
command mentioned above.
2. Add
web_set_sockets_option("MAX_CONNECTIONS_PER_HOST","1"); at
the very beginning of the script.
This forces a single connection to the server thus
eliminating the possibility of the server prematurely shutting down an existing
connection and causing errors when LoadRunner sends data using that connection.
3. Disable webpage breakdown if HTTPS protocol
(SSL) is being used and there is a proxy server in-between the client
(LoadRunner) and the server under test. To disable webpage breakdown from the
Controller:
a. Go to
Diagnostics->Configuration.
b. Select "Disable" tab for
"Web Page Diagnostics"
c. Click "OK" to close the
diaglogue to complete the setup
4. If you have generated your script using WinInet
options then use the WinInet Replay engine. To do so, go to Run-Time Settings
-> Preferences -> Select "WinInet Replay Engine instead of Sockets
(Windows Only)."
Error: "SSL State: error in SSLv3 write client
certificate B..." while replaying in Socket mode
Error: "SSL protocol error when attempting to
connect with host" while replaying a Web protocol script
Add all of the certificates in the certificate
hierarchy for the SSL certificate to a .pem file (e.g. certFile.pem) and
include this .pem file by adding the following line at the beginning of the
script:
web_set_certificate_ex(
"CertFilePath=certFile.pem", "CertFormat=PEM", ...LAST);
web_set_sockets_option("LOAD_VERIFY_FILE",
"certFile.pem");
Error -27791 : "server name" has shut
down the connection prematurely
To Resolve this, you can try adding the below
command:
web_set_sockets_option("MAX_CONNECTIONS_PER_HOST","1"); at the very beginning of the script.
If you still get the same error then you can try
the below command (add it after the previous one):
web_set_sockets_option("IGNORE_PREMATURE_SHUTDOWN",
"1")
Error: SSL protocol error when attempting to
connect with host "xxx"
Try to check the certificate and connection using
openssl with this sentence from CMD:
openssl s_client -connect :2443
or
openssl s_client -connect :443
This will show the certificate information. If not,
application has a certificate problem and need to check with application owners
/ server admins.
