SSH works for ec2 Ubuntu 20 Instance. No other Outgoing/Incoming traffic is working

ng flag

I have an ec2 instance, a postgres database rds instance that share the same vpc. I recently bumped up the capacity of my ec2 instance to xlarge ec2. I setup the server like you normally would with nginx/phusion passenger. I was able to deploy changes with great succession before then. Now I receive network cannot be reached. I don't know where to look/who to ask. I've been working on this issue for 14 hours straight. How can give my ec2 instance back access to the internet (incoming/outgoing)? I cannot do apt-get package or update.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
