To fix this issue use the following workaround.

  1. Access IWSVA as root via SSH

  2. Create a copy of /var/iwss/reverse_proxy/conf/main.conf file:

    # cp /var/iwss/reverse_proxy/conf/main.conf /var/iwss/reverse_proxy/conf/main.conf.COPY

  3. Use vi or vim to open and edit the /var/iwss/reverse_proxy/conf/main.conf file:

    # vim /var/iwss/reverse_proxy/conf/main.conf

  4. Add/edit the "client_max_body_size" after the "http {" line.

    For example:
    client_max_body_size 20M;

  5. Save the change and restart all IWSVA services by running this command:

    # /usr/iwss/rcIwss restart
