Firmware upgrade 7.4.0 throws EOF occurred in violation of protocol (_ssl.c:2393)

[tubatodd]

When attempting to use a previously working (Fortigate FW 7.2.3 to 7.2.4) ansible playbook to upgrade from Fortigate 7.2.4 to 7.4.0, I am getting the following error

  File "/tmp/ansible_fortinet.fortios.fortios_monitor_payload_wnctly95/ansible_fortinet.fortios.fortios_monitor_payload.zip/ansible/module_utils/connection.py", line 200, in __rpc__
ansible.module_utils.connection.ConnectionError: Could not connect to https://10.8.24.30:443/api/v2/monitor/system/firmware/upgrade?vdom=root&access_token=idghG34dn3k61N5H3zbrc33zyQtymp: EOF occurred in violation of protocol (_ssl.c:2393)

The task content looks like the following.

- name: "Upgrade Firmware"
  register: result
  fortinet.fortios.fortios_monitor:
    selector: 'upgrade.system.firmware'
    params:
      source: "upload"
      filename: "{{ _fw_firmware_version_filename }}.out"
      file_content: "{{ lookup( 'file', '{{ _fortigate_firmware_path_full_unarchived }}') | string | b64encode }}"

I've confirmed the variables are correct and that .out file exists. I've verified all of my auth setup works by trying something simple like

- name: "Reboot Test"
  register: result
  fortinet.fortios.fortios_monitor:
    selector: 'reboot.system.os'

The Fortigate rebooted as expected.

Hi @tubatodd ,

Thank you for bring up this issue, your script works well on my side, I notice the error said EOF occurred in violation of protocol (_ssl.c:2393), and search it on other forums, they said that may be caused by proxy issue or openssl version. I didn't use any proxy and my openssl version is OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022), could you check it on your side and let me know.

Thanks, Maxx
