Common Configuration Solutions:

Login page displays "Unable to renew license"

You see the following error message on frevvo's login page when you try to access the login page in your browser at http://<yourhost><port>/frevvo/web/login

   "Unable to renew license for 1 attempt(s). Your license will expire in 2 day(s). Please contact frevvo for help."

You will also see the following error in the tomcat log file:

WARNING: License monitor: failed to authorize start up for 0 attempts. Next attempt in 1 hours.

There are a few possible causes of this:

Incorrect Java Version

This is often caused by running your frevvo Form Server under an older version of Java/JDK. Please follow the steps in the JDK Prerequisite page. Then restart your frevvo Server.

Incorrect License Key

This may also be caused by an incorrect string content in the license key.  To check the license, login via superuser and then click "Server Configuration". You can also check the users schema resource table in your database. This table has an entry with the license information.

Java unable to validate certificate

Sometimes Java is not able to validate frevvo license server certificate. In this case you may see the following error in the tomcat log file:

<timestamp> |-ERROR [LicMon] [c.f.s.s.LicenseMonitor] - Could not process startup request. Got: sun.security.validator.ValidatorException: 
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested
target

This may happen if you started using another application which forces the use of their own root certificate. To correct this, add the frevvo certificate to your server's Java cacerts, which means we tell Java to 'trust this cert; no need to validate'. However, you will have to do this again when you update the java install and or we update our certificate. Here are the steps:

1. Download the app.frevvo.com https certificate using your browser and save it as .cer file.
2. Download portecle (http://portecle.sourceforge.net/)
3. Start portecle.jar
4. Open the keystore file from the java version frevvo uses (example: c:\program files\java\jdk1.8.0_66\jre\lib\security\cacerts)
5. Choose tools > import trusted certificate, select the cer file downloaded before, hit the ok, ok, yes, enter an alias + hit ok, ok
6. Choose file > save keystore
7. Close portecle
8. Restart frevvo

"Unable to contact license server"

This may be due to your external http traffic being routed through a proxy server.

If your company uses a proxy server,  your  Form Server may not be able to communicate with the license server directly.  has configuration parameters to enable communication from the Form Server to the license server via your proxy.

1. Edit the following parameters in <frevvo-home>/tomcat/conf/frevvo-config.properties.
2. Remove the # before the properties. Do NOT remove the # in front of the HTTP Proxy Configuration for licensing comment
3. Add the values for your installation.
4. Save the changes
   
   

# HTTP Proxy Configuration for licensing
#frevvo.proxy.host=<your HTTP Proxy Host>
#frevvo.proxy.port=<HTTP Proxy port>
#frevvo.proxy.username=<HTTP username>
#frevvo.proxy.password=<HTTP password>
#frevvo.proxy.ntlm=<true or false> - Set frevvo.proxy.ldap to true to enable NTLM authentication proxy access.

The trial license fails to install

Sometimes, especially on Windows, the license is not accepted. If so, please restart your frevvo server and try again. Please check the frevvo forum or contact us for additional help.

More License Issues

License issues have several common causes. A proxy server can be the cause of these error messages.

2. Open a browser on your frevvo server machine and try to reach the url: https://www.frevvo.com/security/securehttp. This server should return the message "You have reached the frevvo licensing server. Thanks for you interest in frevvo .".
3. Second open the log files in <frevvo installdir>/frevvo/tomcat/logs and scan for license related error messages.
4. Read solutions for proxy server configurations if the log file indicates that your frevvo server is unable to contact the license server.
