Resolved upstream timed out (110: Connection timed out) while connecting to upstream

[rhand]

Adding

[ext-wp-toolkit]
wpCliTimeoutHeavy = 3600
wpCliTimeoutMedium = 600
wpCliTimeoutRegular = 600
wpCliTimeoutMaintenanceTimeout = 360

based on https://support.plesk.com/hc/en-us/...ed-working-in-60-seconds-so-it-was-terminated seems to help

Only when I go to plugin installation page I still get timeouts . Do have api.wordpress.org added to /etc/hosts and as mentioned Plesk firewall replaced by TransIP firewall which block no outgoing traffic.

An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums.

and error in log

similar error repeated connecting to WordPress api as I have to install a plug-in from the dashboard I also have in WP Toolkit:

[2023-09-29 04:11:06.090] 73516:6516322b0cf36 ERR [extension/wp-toolkit] Unable to retrieve data by "https: //api.wordpress.org/plugins/info/1.1/?action=query_plugins&request[page]=1&request[per_page]=40&request[search]=*Query+Monitor*&request[fields][description]=0&request[fields][short_description]=1"

is also shown in `tail -20 /var/log/plesk/panel.log` so despite the fact that I updated name server:

cat /etc/resolv.conf
# Generated by NetworkManager
search nl
#nameserver 195.8.195.8

#nameserver 2a01:7c8:7000:195:0:135:195:135
nameserver 8.8.8.8

and added api.wordpress.org to hosts file

cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4 localhost4.localdomain4
::1 localhost.localdomain localhost localhost6 localhost6.localdomain6

66.155.40.202 api.wordpress.org

xx.xx.xxxx.180 xxxbeheer.nl xxxbeheer

turned off Plesk Firewall and have only transip.nl firewall turned on I still cannot ping the api

ping api.wordpress.org
PING api.wordpress.org (66.155.40.202) 56(84) bytes of data.
^C
--- api.wordpress.org ping statistics ---
10 packets transmitted, 0 received, 100% packet loss, time 9251ms

and locally I can

ping api.wordpress.org

But what could block the access if I do not use Mod Security, Plesk Firewall and only TransIP firewall for incoming ports?

I checked ports

based on thread How to detect if a network is blocking outgoing ports? to check for closed outgoing ports. Port 443 for https and 80 for http are closed outgoing ports. Do need these open.. or at least for api.wordpress.org

Also solved. Somehow I had added the wrong ip for api.wordpress.org to `/etc/hosts` . I needed

198.143.164.251 api.wordpress.org
