I885WCAG2 A 2.4.3: When 'tabindex' is used the tab order may become incorrect
With 'tabindex', changes to the page can easily change the tab order such that it no longer follows logical relationships and sequences in the content. So, you should manually check any pages that use 'tabindex' to be sure they still make sense. See WCAG2 Failure F44.

W874WCAG2 A 2.4.1: Add a skip navigation link as the first link on the page
If your document has structure then you should add a skip navigation link to make it easier for accessible users to get to the page's content. To ensure detection, skip navigation links should point to a <main> element, or an element with role='main'. See Understanding 2.4.1, and Skip Navigation.

E8661WCAG2 A 1.1.1/1.3.1/3.3.2/4.1.2: User interface controls without a label should have an accessible name
Use the 'aria-label', 'aria-labelledby', or where appropriate 'value', attributes to label controls when the visual design cannot accommodate the label (for example, if there is no text on the screen that can be identified as a label) or where it might be confusing or not possible to use a label. User agents, including assisting technology, can use these attributes. See WCAG2 Failure F68.

E9542WCAG2 A 4.1.2: Interactive elements are not allowed here
When using ARIA roles there are additional rules where interactive elements may appear. This error may also be caused by incorrectly nesting tags, missing end tags, or similar structural issues. So if it is not obvious what is wrong, fix any structural issues first. See ARIA in HTML.

E956WCAG2 A 4.1.2: The value of the 'role' attribute is not valid for this element
Elements can only have specific roles as defined by the ARIA specification. So, you may be better off using a more appropriate element for this role. See ARIA in HTML.

Describe the purpose of a link by providing descriptive text as the content of the element, or provide an 'aria-label' or 'aria-labelledby' attribute. The description lets a user distinguish this link from other links in the Web page and helps the user determine whether to follow the link. The URL of the destination is generally not sufficiently descriptive. See WCAG2 HTML Technique H30.

Describe the purpose of a link by providing descriptive text as the content of the element, or provide an 'aria-label' or 'aria-labelledby' attribute. The description lets a user distinguish this link from other links in the Web page and helps the user determine whether to follow the link. The URL of the destination is generally not sufficiently descriptive. See WCAG2 HTML Technique H30.

E9542WCAG2 A 4.1.2: Interactive elements are not allowed here
When using ARIA roles there are additional rules where interactive elements may appear. This error may also be caused by incorrectly nesting tags, missing end tags, or similar structural issues. So if it is not obvious what is wrong, fix any structural issues first. See ARIA in HTML.

E956WCAG2 A 4.1.2: The value of the 'role' attribute is not valid for this element
Elements can only have specific roles as defined by the ARIA specification. So, you may be better off using a more appropriate element for this role. See ARIA in HTML.

E622HTML: The 'id' attribute does not have a valid value: It does not contain a valid ID. It must contain at least one character and must not contain any space characters
The HTML specification being tested against defines certain valid values for each attribute. Usually a list of valid values will be displayed when you see this message. Note that many values must be in lower case in XHTML, including the 'x' in numeric hex entity references. Also note that what values are allowed varies from standard to standard.

1 In dieser Episode erklärt Dr. Katharina Sandtner, Ärztliche Leiterin des Lanserhof Lans, das medizinische Konzept der Apherese – ein therapeutisches Verfahren zur Blutreinigung, bei dem Entzündungsmarker, Stoffwechselabfallprodukte und andere potenziell schädliche Substanzen aus dem Blut entfernt werden.

2 <p>
2 Eingesetzt sowohl vorbeugend als auch therapeutisch, gewinnt die Apherese zunehmend an Bedeutung – etwa bei Herz-Kreislauf-Erkrankungen, Autoimmunerkrankungen und in der Langlebigkeitsmedizin.

W868WCAG2 A 2.4.4: Different adjacent links with the same link text 'socials-link'
If you have adjacent links to different places, but with the same link text (when read aloud), it can be confusing to the user. So, you should either change the link text or add a unique 'aria-label' or 'aria-labelledby' attribute to each link. See Understanding 2.4.4.
