Your reverse proxy makes a plain http connection `proxy_pass http://www.abc.xyz/;` and probably the backend site doesn't allow plain http and sends a redirect to the https version of their site. Try `proxy_pass https://www.abc.xyz/;` and that redirect shouldn't be necessary anymore. But the backend site may have other checks and controls to ensure that it always accessed by its own URL to prevent reverse proxying and other abuse

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.
