The standard logout command <code>abb-cli -l<\/code> fails because the agent insists on contacting the original server to de-register.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide shows you how to manually break the connection and reset the agent without a full reinstallation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Problem: abb-cli -l Fails Without a Connection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Normally, you would use <code>abb-cli -l<\/code> (logout) or <code>abb-cli setup<\/code> to reconfigure the agent. However, if the agent cannot reach the original NAS (e.g., after a server migration or IP change), it will return an error:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><em>&#8220;Internet error. Please check your Internet connection&#8230; Authentication failed.&#8221;<\/em><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Since the agent is stuck in a &#8220;logout loop,&#8221; you must clear the configuration at the file level.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Step-by-Step: Manual Connection Reset<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If the regular logout is impossible, a manual intervention in the agent&#8217;s SQLite databases is required. Follow these steps:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Stop the Service<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First, stop the agent&#8217;s background service so the database files are not locked:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div class=\"wp-block-kevinbatdorf-code-block-pro\" data-code-block-pro-font-family=\"Code-Pro-JetBrains-Mono\" style=\"font-size:.875rem;font-family:Code-Pro-JetBrains-Mono,ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,monospace;line-height:1.25rem;--cbp-tab-width:2;tab-size:var(--cbp-tab-width, 2)\"><span style=\"display:block;padding:16px 0 0 16px;margin-bottom:-1px;width:100%;text-align:left;background-color:#24292e\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"54\" height=\"14\" viewBox=\"0 0 54 14\"><g fill=\"none\" fill-rule=\"evenodd\" transform=\"translate(1 1)\"><circle cx=\"6\" cy=\"6\" r=\"6\" fill=\"#FF5F56\" stroke=\"#E0443E\" stroke-width=\".5\"><\/circle><circle cx=\"26\" cy=\"6\" r=\"6\" fill=\"#FFBD2E\" stroke=\"#DEA123\" stroke-width=\".5\"><\/circle><circle cx=\"46\" cy=\"6\" r=\"6\" fill=\"#27C93F\" stroke=\"#1AAB29\" stroke-width=\".5\"><\/circle><\/g><\/svg><\/span><span role=\"button\" tabindex=\"0\" style=\"color:#e1e4e8;display:none\" aria-label=\"Copy\" class=\"code-block-pro-copy-button\"><pre class=\"code-block-pro-copy-button-pre\" aria-hidden=\"true\"><textarea class=\"code-block-pro-copy-button-textarea\" tabindex=\"-1\" aria-hidden=\"true\" readonly>sudo systemctl stop synology-active-backup-business-linux-service\n<\/textarea><\/pre><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" style=\"width:24px;height:24px\" fill=\"none\" viewBox=\"0 0 24 24\" stroke=\"currentColor\" stroke-width=\"2\"><path class=\"with-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M9 5H7a2 2 0 00-2 2v12a2 2 0 002 2h10a2 2 0 002-2V7a2 2 0 00-2-2h-2M9 5a2 2 0 002 2h2a2 2 0 002-2M9 5a2 2 0 012-2h2a2 2 0 012 2m-6 9l2 2 4-4\"><\/path><path class=\"without-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M9 5H7a2 2 0 00-2 2v12a2 2 0 002 2h10a2 2 0 002-2V7a2 2 0 00-2-2h-2M9 5a2 2 0 002 2h2a2 2 0 002-2M9 5a2 2 0 012-2h2a2 2 0 012 2\"><\/path><\/svg><\/span><pre class=\"shiki github-dark\" style=\"background-color: #24292e\" tabindex=\"0\"><code><span class=\"line\"><span style=\"color: #B392F0\">sudo<\/span><span style=\"color: #E1E4E8\"> <\/span><span style=\"color: #9ECBFF\">systemctl<\/span><span style=\"color: #E1E4E8\"> <\/span><span style=\"color: #9ECBFF\">stop<\/span><span style=\"color: #E1E4E8\"> <\/span><span style=\"color: #9ECBFF\">synology-active-backup-business-linux-service<\/span><\/span>\n<span class=\"line\"><\/span><\/code><\/pre><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">2.
