Hi,

try adding the relaxedQueryChars parameter in the Connector of the server.xml. I.e:
 

<Connector port="80" 
           protocol="HTTP/1.1"
           maxThreads="150"
           connectionTimeout="20000"
           redirectPort="443"
           relaxedQueryChars="[,],{,}"
             />

Regards.

Hello .. Good night. Unfortunately 

<Connector port="80" 
           protocol="HTTP/1.1"
           maxThreads="150"
           connectionTimeout="20000"
           redirectPort="443"
           relaxedQueryChars="[,],{,}"
             />

it had no effect. Could help? 

Where in the server.xml file should I add?

Thanks.

Please look at the tomcat documentation for relaxedQueryChars: https://tomcat.apache.org/tomcat-8.5-doc/config/http.html
