It looks like your name resolution has changed, can you show us your ansible hosts file, your /etc/resolv.conf and your /etc/hosts ? ---

do you have delegate\_to or connection: local set on that task? ---

Hi Brian. From hosts: … [webservers] web[01:02] web[04:05] … resolv.conf contains the nameserver of my router. from etc/hosts: 45.56.XXX.XXX web1 104.237.XXX.XXX web2 104.239.XXX.XXX web4 104.130.XXX.XXX web5 Neither the ansible hosts file or /etc/hosts are changing mid run of the ansible script in the same place every time. This is definitely a bug in Ansible. Thanks for your input. 🙂 ---

but on the task that is hitting localhost, do you have a delegate\_to/connection: local there? ---

> > but on the task that is hitting localhost, do you have a delegate\_to/connection: local there? No, that’s the bug I’m reporting. If I comment out 153 # - name: PHP | Copy over fpm-php pools 154 # synchronize: src=/obsidian/ansible/files/etc-php5/fpm/pool.d dest=/etc/php5/fpm/ recursive=yes delete=yes 155 # tags: php Then the rest of the playbook works correctly. The synchronize command specifically is using 127.0.0.1 instead of the machine IPs. ---

By default synchronize runs as a local action to copy files from the ansible host to the remote server, do you have localhost or 127.0.0.1 defined in your hosts file and connection variables set? ---

Thank you Brian!!! Following some advice on using the linode module I added this to the ansible hosts file: 20 [local] 21 localhost This broke only the synchronize command. Strange.
