In the configuration file config.inc. php the configuration for proxy instead of being:
[proxy]
; The HTTP proxy configuration to use
; http_proxy = “http: // username: password@192.168.1.1: 8080”
; https_proxy = “https: // username: password@192.168.1.1: 8080”
Should be:
[proxy]
; The HTTP proxy configuration to use
; http_proxy = “http: // username: password@192.168.1.1: 8080”
; https_proxy = “http: // username: password@192.168.1.1: 8080”
That in both configurations for http_proxy and https_proxy it should only take http://
Thats can resolve the error of:
PHP Fatal error: Uncaught GuzzleHttp \ Exception \ ConnectException: cURL error 35: error: 1408F10B: SSL
OJS 3.3.0.6
Ubuntu 20.04 Server LTS
