ok guys I have the anwser, on apache server there exist SSLRenegBufferSize parameter https://httpd.apache.org/docs/current/mod/mod_ssl.html#sslrenegbuffersize

When you have F5 configured as SSL bridging by default it renegotiates SSL in serverssl profile, which could cause the error in apache ssl.log AH02018: request body exceeds maximum size (131072) for SSL buffer.

There are 3 possible fixes for it:

2. Change SSLRenegBufferSize to higher on Apache server
3. Change Renegotiate size in serverssl profile the same as Apache

What I tried was increasing the SSLRenegBufferSize parameter in Apache, but there are several solutions provided by F5 support.
